Input Voltage
|
18 – 60VDC; 24 – 30 VAC (RMS)
|
|
Isolation Voltage (Dielectric withstand)
|
Meets IEC 950 for one minute.
1,500 VAC: Output/Input
1,500 VAC: Input/Safety GND

|
Load Regulation
|
+/-0.5% at 10% load to full rated load
|
|
Over Load Protection (OLP)
|
When the average power rating exceeds 125% to 150% of maximum power, output voltages reduced to a safe dissipation level; protects against short circuit of any output
|
|
No Load Protection
|
No damage to power supply when operating at no load
|
|
Transient Protection
|
No voltage spike at power-on, power-off, or power failure
|
|
Power Distribution
|
+12.6VDC at 1.0 A maximum
|
|
Power Consumption
|
6 watts max. @ 18VDC input, 12.6VDC output
|
|
Noise and Ripple
|
+/-40mV peak-to-peak of output voltage (typical)
|
|
MTBF (Mean Time Before Failure)
|
Greater than 60,000 hours with typical load operating at 20°C temperature (calculated according to MIL-HDBK-217E)
