1.1 Introduction

The models PeakTech ^® 1525 / 1530 / 1535 / 1560 Switching Mode DC Power Supplies provide high power output with it small size and lightweight. They are suitable for a variety of uses, especially for DC operated radio equipment.

Please read through this operation instruction carefully and follow the instructions to prevent from abuse or misuse. This manual must be kept for reference at anytime in need.

NOTE:

Laboratory Power Supplies are not designed for charging batteries. Any use of this type can cause serious damage to the device, which are exempt from any legal claims whatever.

Operation with inductive loads

Please note that our power supplies are designed for resistive or capacitive loads.

When using an inductive load, e.g. electric motors, it may damage the power supply.

The power supply has protective functions against short circuit and overload, but it is not protected against inductive reverse voltages, which can be caused by electric motors or batteries.

2. Features

• Lightweight and Small Size: Switching mode power supply has the advantages of lightweight and small size. Comparing with linear mode power with the same power output, it is much lighter and smaller.
• High Efficiency: The unit is operated with efficiency over 85% (P 1525/1535); 87% (P 1530); 86% (P 1560); under the best condition.
• Overload Protection: The constant current limiting protection is adopted to prevent from overload. The overload indicator will be lighted up when the unit is overloaded.
• Over Temperature Protection: The over temperature circuitry is functioned when the unit is over a certain high temperature to prevent the unit from damage by the high temperature. When the circuitry is functioned, the output voltage and current will drop down to a safety value.
• Over Voltage Protection: The over voltage circuitry the unit and the loading equipment form damage by abnormal high output voltage.
• High RFI Stability: The high protection circuitry against RFI (Radio Frequency Interference) provides a stable operation.
• Variable Voltage Output: The variable range of output voltages enables good fits with various uses.

Check your load and output setting. Allow the unit to cool down for at least 30 minutes. Check if any of the ventilation is blocked, check enough clearance around power supply. Listen carefully for the short wind noise from the cooling fan when you turn on the unit again. If you cannot hear this routine self test wind noise on switch on, the fan is fault and do not use the power supply, contact your agent.

11.3 OLP: Overload protection

Normally the overload protection is sustained by the CC constant current mode.

When the CC mode fails and goes undetected, it may cause serious damage to your test piece or load.

The OLP is to minimize the extent of damage to your loads as power supplies do fail some day.

Switch off your power supply as soon as you see this warning as shown below.

OLP V 8.8.8. A C.V. C.C. REAR CONTROL

To reset this warning, switch off the unit and remove all loading.

Switch the unit back on again and double check with caution.
