800 W Model 4
1200 W Model 4
2000 W Model 2
The difference in output voltage and output current between the master unit and the slave unit must be within 1% of the rated value.
Danger: Risk of electric shock. Before touching the output terminals, turn off the power switch. After assembling the output cables, install the output protection cover.
Note If parallel operation is not in use, disconnect all parallel connections.
3.1 Parallel Operation Steps
Note
When grounding the output terminals, connect the same-polarity output terminals (+ or -) of the master and slave units to the chassis terminal. Improper connection may damage the power supply and load.
For long wires, phase shifts due to wiring inductance and capacitance may cause oscillations. To prevent this, connect an electrolytic capacitor (ranging from hundreds of F to tens of thousands of F) at the load end as needed. The capacitor’s voltage rating must be at least 120% of the UDP5000 series rated output voltage.
Twist the + and – wires together and keep them as short as possible when connecting.
Example: Setting Parallel Operation on UDP5040-40 1. Turn off all power switches. 2. Remove the output protection cover. 3. Connect the analog interface.
Use a double-ended female header cable (dual-row female header 2×10 pins, 2.54mm pitch) to connect the analog interface of the parallel power supplies.
17
UDP5000 Series Programmable DC Power Supplies
4. Parallel-connect the output terminals of all units to a wire connector using appropriate wires, then connect to the load.
Ground the same-polarity output terminals (+ or -) of the master and slave units. Use wires with sufficient current capacity for the output connection. Ensure equal length and cross-sectional area for all wires connecting each UDP5000 series unit to the intermediate terminal block. Keep wire lengths 50 cm to minimize resistance and inductance. Separate the analog interface wiring from the output wiring as much as possible to reduce interference.
Parallel Operation Load Connection Example (2 Slave Units) One side of the parallel system is connected to the chassis terminal.
5. Install the output protection cover.

22
UDP5000 Series Programmable DC Power Supplies
Output automatically turns off immediately after turning.
Great Output Fluctuation Case Output fluctuations occasionally increase. Relocating the installation site causes greater fluctuations. Significant fluctuations occur during external control Fluctuations worsen after replacing output wires.
Output Unstable Case
When enabling output, changing the voltage/current value may cause instability.
The output voltage or current fluctuates during operation.
Output voltage deviates when power is applied. Output voltage does not drop even after turning off the output.
Output voltage deviates from the set value.
Is OVP enabled? Is OTP enabled? Is external voltage control enabled?
Set the OVP value higher than the voltage setting. An abnormal temperature rise may trigger OTP. Check the operating environment, address any overheating causes, and restart the output. If the external voltage control is enabled, pressing the output button will only exit external voltage control mode and will not activate output.
Check Item Is the input voltage outside the specified range?
Is there a strong magnetic or electric field source nearby?
Is the external voltage noise excessive?
Is the sampling wire connected?
Solution Ensure the input voltage remains within the rated range. Move the instrument away from interference sources or mitigate noise by twisting output wires Use appropriate filtering or shielding techniques to reduce voltage noise. If remote sense compensation is disabled, reconnect the voltage sampling spring piece.
Check Item
Is the operation mode switching between CV CC or CC CV?
Is the instrument operating in single-controlled parallel mode? Have the sense wires or voltage sampling spring pieces become disconnected?
Is the operation mode repeatedly switching between CC/CV?
Are there loose connections or breaks in the sampling wires or output wires?
Are there load current peaks or fluctuations?
Has the instrument been powered on for at least 30 minutes?
Is the discharge load setting disabled?
Has the internal resistance value been configured?
Are the screws securing the voltage sampling spring piece loose?
Solution Set the output voltage or
current limit higher than the current setting. If the current setting is already at the maximum, consider a power supply with a higher output voltage or current capacity. Performance may be lower in parallel operation than when the instrument is used alone. If remote sense compensation is disabled, reconnect the voltage sampling spring piece. If remote sensing compensation causes oscillations, install a capacitor at the load terminal. If circuit damage is suspected, immediately stop using the instrument and arrange for repairs.
Turn off the power switch and check all wiring connections.
If peak currents exceed the set value, increase the current setting or switch to a higher-capacity power supply. The instrument should warm up for at least 30 minutes before use. If the discharge load is disabled, residual voltage may remain after turning off the output. Set the discharge load to On/Auto to ensure proper voltage dissipation. Set the internal resistance value to zero. Secure the voltage sampling spring piece by tightening the screws at the voltage sampling terminals and rear output terminals.
