Keep this manual in a safe place for quick reference at all times.
This manual contains important safety and operation instructions for correct use of the power
supply. Read through the manual and pay special attention to the markings and labels of this
Pay special attention to these two types of notices used in this manual
Failure to observe this warning may cause injury to persons and damage to power
Failure to observe this warning may result in damage to equipment
WARNING:
1. Do not use this power supply near water.
2. Do not operate or touch this power supply with wet hands.
3. Do not open the casing of the power supply when it is connected to ac mains.
4. Refer all servicing to qualified service personnel only.
5. Before replacing the AC fuse at AC socket, find out and clear up the cause first.
6. Replace the AC fuse with the same type and rating as the original fuse.
7. The max. output voltage of Model NTP-5561 is 60VDC, avoid touch the metal contact part of the
output terminals.
CAUTION:
1. Use a grounded 3 pin AC source.
2. This unit is for indoor use only.
3. Do not operate or place this unit in a humid, dusty, in direct sunlight location or near any heat source.
4. Before plugging into local AC mains, check with the rating label at the back of the unit.
5. Do not block any ventilation openings of the unit.
6. This unit must be used within the specified rating, regular excessive continuous loading may cause
damage to the power supply.
7. The gauge size of input power cable must be at least 0.75mm
must not exceed 3m.

This manual contains important safety and operation instructions for correct use of the power supply. Read through the manual and pay special attention to the markings and labels of this unit and equipment to be connected.
- Page 2 INTRODUCTION This series of 100W Switching Mode Power Supplies with Current Limiting Control is designed with the objectives of high accuracy, compactness and easy portability. Rotary encoder tuning with MCU are used for voltage and current control. 4 digit display LCD of voltage and current for high precision. This power supply is ideal for trouble shooting circuit boards or devices which require two or three different input voltages such as 3V or 5V, 12V and 1-36V.
- Page 3 OPERATIONS Basic Mode of Operation This power supply is designed to operate as a constant voltage source or as a constant current source. Automatic crossover to either mode of operation occurs when the load condition changes as following: Constant Voltage (CV), Automatic crossover & Constant Current (CC) The power supply functions as a constant voltage source (CV) as long as the load current is less than the preset current limiting value.
- Page 4 DIAGRAM SHOWING CIRCUIT BOARD OR DEVICE Connecting outputs in series (using NTP-5531 as an example) You can have a 17V fixed output by connecting the 5V in series with the 12V outputs. The 2 outputs (Aux.1) can be connected in series to make a variable 5V to 41V with current 1.8A (Fig. 2) The 3 outputs can be connected in series to make a variable 17V to 53V with current 0.8A, (Fig.
- Page 5 Tracking Output Over Voltage Protection (Fault Code F01) This is to protect the connected load in the event that the output voltage control circuit malfunctions, the maximum output voltage will not exceed 10% (min. 1.7V) of the adjusted voltage value at the time of the operation. Protection will be triggered and the output power will be cut off and ouP warning appears as below.
