NOTES: 1. Safety agency approvals are for the above listed models in PCB form. To order a model with a metallic L-bracket or box, change suffix "A" to "B" for L-bracket form, to "C" for enclosed form, e.g. PM25-31C.

2. All models may be operated at no-load without damage. At no-load, output voltage tolerance increases to ±10%.

3. Ripple and noise is maximum peak-to-peak voltage value measured at output within 20 MHz bandwidth, at rated line voltage and
