Input:
Input Voltage
18 - 60 VDC, 24 - 30 VRMS
Isolation Voltage
(Dielectric withstand)
Meets IEC 950 for one minute
1500 VAC: Output/Input
1500 VAC: Input/Safety GND
1500 VAC: Output/Case
Output:
Output Voltage
12.6 VDC
Output Current
1.0 A
Load Regulation
±5% at 10% load to full-rated load
Over Load Protection
(OLP) When the average power rating exceeds 125%-
150% of the maximum power, the output voltage is
reduced to a safe dissipation level. This action protects
against output short circuit.
No Load Operation
No damage to power supply when operating at no load.
Transient Protection
No voltage spike at power-on, power-off, or power
failure.
