Dimensions : 101.6 x 50.8 x 30.0mm

Watt : 40W


This series of compact, open PCB constructed, AC-DC switching power supplies are capable of delivering 30-48 watts of continuous output power at convection cooling. They operate at 90-264 VAC input voltage ithout the need of voltage ion, and are suited for medical, information technology and industrial applications. Approval to both EN60601-1 and EN60950-1 Safety Standards improves design-in time and reduces end equipment compliance costs.


  • Medical and ITE approvals
  • Compact size 2” x4” x1.18”
  • Single, dual and triple outputs
  • Wide-range input 90-264 VAC
  • Low earth leakage current
  • Level B emissions RoHS compliant

1. Safety approvals are for PCB form only. To order unit with cover fitted, change suffix “A” to “C”.

2. The output voltages of a multiple output model may go outside of the stated tolerance when an output load current is out of stated limits. All models may be operated at no-load without damage.

3. 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.
