Output Voltage/Current Rating Chart

Notes:

1. Safety approvals are for PCB form only. To order models with metallic L-bracket or box, change suffix "A" to "B" for L-bracket form, to "C" for enclosed form (see Outline Drawing of Cased Internal Switchers), e.g. PM100-14C.
2. Ripple and noise is maximum peak to peak voltage value measured at output within 20 MHz bandwidth, at rated line voltage and output load ranges, and with a 10 μF tantalum capacitor in parallel with a 0.1 μF ceramic capacitor across the output.

Output Power Derating Curve

The output power derating curve shows the relationship between ambient temperature and maximum output power. The power supply can deliver 100% of its rated output power up to an ambient temperature of +50°C. Beyond +50°C, the output power derates linearly, reaching 50% of its rated power at +70°C.
