Product Usage Instructions

Installation Guidelines
Ensure installation clearance of 40mm from top, 20mm from bottom, and 5mm from the left and right side when loaded with full power permanently. For adjacent heat sources, maintain a 15mm clearance.

Output Voltage Adjustment
}The voltage adjustment range is between 29-33V for PSC-15124 and 56-65V for PSC-15148. Use caution when adjusting to prevent overloading or underpowering connected devices.

Protection Features:
The power supply has various protection mechanisms:

Constant current limiting at 150% rated power or in case of a short circuit.
Automatic shutdown if the output voltage drops to 40% of the rating.
Latch-off mode for protection against overvoltage.
Automatic recovery after temperature decrease for overtemperature protection.

Maintenance and Safety
Regularly check for proper functioning of the power supply. Ensure that the system meets safety standards and follows the installation guidelines to prevent any hazards.

FAQ

Q: What should I do if the power supply shuts down due to protection mechanisms?
A: If the power supply shuts down due to protection mechanisms, allow it to cool down before re-powering on. If the issue persists after multiple shutdowns, consult the user manual for further instructions.
Q: Can the power supply be used in equipment that requires EMC compliance?
A: Yes, the power supply can be used in equipment that requires EMC compliance. Ensure that the final equipment still meets EMC directives after installing the power supply.

DC OK Relay Contact

Contact Close	When the output voltage reaches the adjusted output voltage.
Contact Open	When the output voltage drop below 45% rated output voltage.
Contact Ratings(max.)	30V/1A resistive load

Peak Load SW1 ON (Mode1) Default setting
T-peak presents while the unit is working within 110%~150%Rating output power. See curve ” B ” for the variation in T-peak between output current and holdup time. If T-peak is more than the time setting in curve “B”, the output current will drop to the constant current limit (I-normal) that is 105% rating power, meanwhile, I- normal and T-normal will be presenting. See curve “A” for the timing back to I-Peak of T-normal and this Mode can use for easy 2-stage battery charger.

Peak Load SW2 OFF (Mode2)
T-peak presents while the unit is working within 110%~150%Rating output power. See curve ” B ” for the variation in T-peak between output current and holdup time. If T-peak is more than the time setting in curve “B”, the output current will be shut down for 3~4 sec, then auto-recovery.

Remote ON/OFF

The PS U can be turned ON/OF F by us ing the “Remote Control” function.
