5. Features and functions

• The SPS 1525 PFC and SPS 1540 PFC mains power supply units use switching network technology with the advantages of weight and size reductions. Switched-mode mains power supply unit use chopped mains voltages and return a broad spectrum of harmonic waves to the mains line, which may cause interference in other devices. To suppress these harmonic waves, a PFC (Power Factor Correction) has been integrated in the product.
• The dc output is dc-isolated and features a fuse disconnector to the mains voltage.
• The output voltage can be adjusted by means of the adjustment control (6) from 3 V to 15 V/DC or for the SPS 1560 from 1V - 15Vm; current limitation is not possible.
• A special feature of the models SPS 1525 PFC und SPS 1540 PFC is a fixed voltage switch on the underside of the device to fix the output voltage to 13.8V / DC .
• The secondary DC connection is effected through two coloured connection jacks.
• For the switched-mode power supply SPS 1560 PFC up to 5A can be collected at the front side and up to 60A at the rear.
• The mains power supply is cooled via a temperature-controlled fan. For this reason, make sure there is an adequate air circulation and lateral distance to obstacles.
• The mains power supply is equipped with an overload protection circuit. This circuit is activated when the maximum permissible current is exceeded due to an overload or short circuit. The red indicator is the overload indicator. If it lights up, the consumer must be disconnected from the mains power supply to avoid damage to the switched-mode mains power supply.

The switched-mode mains power supply unit is not a charger. To charge batteries, use suitable chargers with a charging current cut-off.

a) Connecting the power cable

1. Connect the provided shockproof power cable to the power connector (12, female) of the mains power supply. Make sure it is plugged properly.
2. Connect the power cable to a shockproof mains socket with protective grounding.

b) Setting the desired output voltage

1. Make sure that there are no consumers connected to the mains power supply.
2. Switch on the mains power supply at the power switch (1). The power indicator (2) should light up.
3. Now use the DC control (6) to set the desired output voltage. The setting can be checked on the display (9).

c) Setting the fixed voltage of 13.8V (only SPS 1525/1540 PFC)

1. Make sure that there are no consumers connected to the mains power supply.
2. Switch on the mains power supply at the power switch (1).
3. Now set the wiper switch (5) underneath the device to the "FIXED 13.8V " position.
4. The output voltage has now been fixed to this values and cannot be changed via the control on the front of the device. The voltage is shown on the display (9).
5. To deactivate the fixed voltage, slide the wiper switch to the opposite direction.

Only change the setting when no consumers are connected! Verify the operating voltages of the consumers first!

d) Connecting a consumer

1. Make sure the consumer is switched off.
2. Verify that the correct output voltage has been set.
3. Connect the plus pole (+) of the consumer to the red terminal screw connector "+" (4), and the minus pole (-) of the consumer to the black terminal screw connector "-" (3).
4. 4-mm standard connectors can be used for connection but should take place via 20A by means of screw terminals. (the jack heads can be screwed on to the front only for the SPS 1525/1540 PFC!).
5. For the switch power unit SPS 1560 PFC up to 5A can be connected at the front safety-jack consumer (automatic current limit) and up to 60A at the rear through high-current terminal jacks.
6. The power consumption of the connected consumers is shown on the current display (8).

Make sure that the consumers are switched off when connected to the switched-mode mains power supply. Sparks may be generated when a consumer which has been switched on is connected to the jacks. This may damage the terminal screw connectors as well as the connected cables.

e) "SENSE" function (only SPS 1560 PFC)

The switched-mode power supply possesses an automatic voltage control for the high-current output. For this, two separate measuring cables are connected parallel to the connecting cables. The potential drop which occurs on the connecting cables is measured on these two measuring cables. The switched-mode power supply compensates this potential drop automatically so that the actually set voltage is pending on the consumer.

Proceed as follows for connection:

1. Always connect the supply cables from the power unit to the consumer. Pay attention to correct polarity.
2. Press the orange-coloured terminal on the SENSE connection inwards with a small screwdriver and insert the cables into the green terminal openings. Check that they are plugged firmly.
3. Now connect the two "SENSE" cables to the consumer observing the correct polarity. The conductor cross-section for the "SENSE" cables must be at least 22AWG (= 0.34mm^2) .
4. Always slacken the connection in the reverse order (first of all the "SENSE" cables and then the connecting cables).

1. Make sure that you contact the SENSE cables as close as possible to the connecting point of the consumer.
2. Short the "SENSE" cables.

f) REMOTE control (only SPS 1560 PFC)

Through the built-in "REMOTE" control connection, the voltage setting can take place with an external voltage source or through an externally adjustable resistance (short "poti") and it's possible to switch the DC output on/off.

The REMOTE connection takes place on the rear REMOTE built-in plug (14).

Preparation of the remote control connection.

1. Turn the central screw of the supplied slide-in jack and remove the front, black contact jack by means of a small turning movement.
2. Draw the five connecting cables with a conductor cross-section of at least 22AWG (=0,34mm^2) through the metal sleeve from the rear. Solder these five cables firmly and carefully to the soldering lugs no.1,2,3,7 and 8 of the black contact jacks.
3. Mark the loose ends of the cables with the corresponding contact numbers (1-3) to rule out any confusion.
4. Insert the black contact jack in the reverse order into the metal sleeve and screw these firmly.

Control through external voltage source

The power unit can be remote-controlled by means of an external voltage source of 0 to 5V/DC over the complete output voltage range.

Proceed as follows for connection:

1. Connect the connecting cable of the REMOTE plug as illustrated.

2. Connection 2 to the plus pole (+) of the voltage supply and connection 3 to the minus pole (+) of the voltage supply

3. Connection 1 is not required.

The voltage on the remote control connection may not exceed 5V.

nnections may not be shorted.

1. Switch off the switched-mode power supply and then connect the REMOTE plug to the rear remote connection. Screw down the external fastening ring.

Turn the voltage of the external voltage source to zero.

1. Slide the rear VOLTAGE REMOTE switch to the "ON" position.

1. Switch the switched-mode power supply on. The desired output voltage can now be set through the external voltage source. Control the complete adjustment area for correct function.
2. If this remote control function is no longer required, the switch to the "OFF" position.

Control through a controllable resistance (poti)

The power unit can be remote-controlled by means of an external poti of 5 KOhm over the complete output voltage range.

Proceed as follows for connection:

1. Connect the connecting cable of the REMOTE plug as illustrated.

2. Connection 1 at one end of the resistance.

3. Connection 2 at the centre sliding contact of the resistance.
4. Connection 3 at the second end of the resistance.

1. Switch off the switched-mode power supply and then connect the REMOTE plug to the rear remote connection. Screw the external fastening ring.

2. Slide the rear VOLTAGE REMOTE switch to the "ON" position.

1. Switch the switched-mode power supply on. The desired output voltage can now be set through the external poti. Control the complete adjustment area for correct function.
2. If this remote control function is no longer desired, move the switch to the "OFF" position

Enable and disable the output

You can use Port 7 and 8 to remote control the output on/off.

• Open Port 7 and 8 if you want to enable the output (default).
• Short Port 7 and 8 if you want to disable the output.

g) Replacing the fuse

If it is no longer possible to switch on the mains power supply, the mains fuse has probably tripped.

Proceed as follows to replace the mains fuse:

1. Switch off the mains power supply and remove all the connection and power cables.
2. Use a suitable screwdriver for slotted screws to prise out the fuse holder on the rear of the device.
3. Replace the defective fuse with a new fine-wire fuse (5 × 20 ~mm) of the same type and rated current, which is as follows: F 3.15 A / 250 V (fast blowing).
4. Press the fuse-link back into the fuse holder until it snaps in properly.
