READ SAFETY INSTRUCTIONS

Servicing:

These products are not customer serviceable. TDK-Lambda UK LTD. and their authorised agents only are permitted to carry out repairs.

Critical Components:

These products are not authorised for use as critical components in nuclear control systems, life support systems or equipment for use in hazardous environments without the express written approval of the Managing Director of TDK-Lambda EMEA.

Product Usage:

These products are designed for use within a host equipment which restricts access to authorised competent personnel.

Environmental:

These products are IPX0, and therefore chemicals/solvents, cleaning agents and other liquids must not be used.

Environment:

This power supply is a switch mode power supply for use in applications within a Pollution Degree 2, overvoltage category II environment. Material Group IIIb PCB's are used within it.

Output Loading:

The output power taken from the power supply must not exceed the rating stated on the power supply label, except as stated in the product limitations in this handbook.

Input Parameters:

This product must be operated within the input parameters stated in the product limitations in this handbook.

End of Life Disposal:

The unit contains components that require special disposal. Make sure that the unit is properly disposed of at the end of its service life and in accordance with local regulations.

RISK OF ELECTRIC SHOCK

High Voltage Warning:

Dangerous voltages are present within the power supply. The professional installer must protect service personnel from inadvertent contact with these dangerous voltages in the end equipment.

This product must be reliably earthed and professionally installed in accordance with the prevailing local electrical wiring regulations and safety standards.

The (+) or (-) output(s) can be earthed or left floating.

An internal fuse protects the unit and must not be replaced by the user. In case of internal defect, the unit must be returned to TDK-Lambda UK LTD or one of their authorised agents.

HOT SURFACE

External Hot Surfaces:

In accordance with local regulations for Health and Safety at work, manufacturers have an obligation to protect service engineers as well as users. In order to comply with this, a label must be fitted to these products which is clearly visible to service personnel accessing the overall equipment, and which legibly warns that surfaces of these products may be hot and must not be touched when the products are in operation.

The ventilation openings on these products must not be impeded. Ensure that there is at least 25mm spacing between any obstruction and the ventilation openings.

The unit cover/chassis is designed to protect skilled personnel from hazards. They must not be used as part of the external covers of any equipment where they may be accessible to operators, since under full load conditions, part or parts of the unit chassis may reach temperatures in excess of those considered safe for operator access.

Special Safety Instructions

Standard Specific Safety Instructions:

Whilst all individual outputs are classed as SELV outputs in accordance with the standard IEC/EN/UL/CSA60950-1 (<60Vdc or 42.4V peak), seriesed combinations of these outputs may exceed these values and become hazardous output voltages.

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Level of Insulation:

Dielectric Strength testing is carried out as follows:

Primary mains circuit to earth: - 1500KVAC, 2121VDC

Primary mains circuits to secondary: 3kVAC, 4142VDC*

*This test is not possible with Y capacitors fitted to the unit as damage to these capacitors will occur. It is also necessary to short circuit the output together and to earth.

Safety Approvals:

UL508

UL/cUL60950-1 ( 2^nd Edition)

IEC / EN60950-1(2 ^nd Edition)

CE marking when applied to any DPP960-xx-3 product indicates compliance with the Low Voltage Directive (2006/95/EC) in that it complies with EN60950-1 ( 2^nd Edition).

Fusing: Internal fuses (F1): Single fuse each phase, T5AH, 500V

Symbols:

AC

EARTH

N - Neutral

L - Live

If the earth terminal of the DPP960-xx-3 PSU is connected to the main incoming earth conductor of the end equipment, the installer must cover the earth symbol with a label bearing the earth symbol of IEC60417-5019.

Input Parameters:

Description Operation

Nominal input voltage 340-575VAC three phase

Input frequency range 47 – 63Hz

Maximum input current 0.36A typical

Output Parameters:

Output Watts	Vout (V)	Adjustment	range (V)	Output current (A)
960W		24 22.5 – 28.5 40
		48 47 - 56 20

Adjusting output voltage beyond the stated range may cause overvoltage protection (OVP) to operate, whereby the output will latch off. To reset for normal operation simply adjust the potentiometer to reduce the output voltage to within its range and cycle the input off then on.

All outputs are SELV except under the following circumstance: Outputs connected in series are non-SELV if the total output voltage exceeds 60Vdc

If the total voltage of outputs connected in series exceed the 60Vdc SELV limit then all outputs must be considered non-SELV.

Non-SELV outputs are hazardous and must not be made user accessible. Consideration must be given to service engineers making inadvertent contact with the output terminals in the end equipment.

All outputs have functional spacing to earth, and due consideration must be given to this in the end product design.

Parallel operation - Up to 2 units may be connected in parallel, output loading 10-90% in parallel mode. Connect up to a maximum of 2 units ensuring the connecting wires used are the same type, gauge and length. This will aid current sharing.

Cooling for unit

The unit must be mounted on a DIN rail and must not be inverted, the input and output connections lowest. As shown in Fig 1.

Front panel indicators:

DC ON - The Green LED is on when the output voltage is >75%.

DC LOW - The red LED is on when the output voltage is between 70 – 90%.

The output can be increased by turning the front panel potentiometer clockwise, turning the potentiometer counter clockwise will decrease the output.

Adjusting output voltage beyond the stated range may cause overvoltage protection (OVP) to clamp the output. To reset for normal operation simply adjust the potentiometer to reduce the output voltage to within its range (see table above)
