Consult the factory for OCP setting.

GENERAL SPECIFICATION

Efficiency: Typical 87%-88% (various with the output

voltage)

Operating Temperature: 0°C to +40°C.

Storage Temperature: -20 to +85°C.

Cooling: Free air convection.

Construction: Impact resistant thermo-plastic

enclosure case.

Switching Frequency: Typical 65KHz.

Circuit Topology: Fixed Frequency Flyback circuit.

Transient Response: Output voltage returns in less than

5.5mS following a 50% load change.

Power Density: 3.14-3.27Watts. / Cubic inch.

Desktop Format.

Safety Standard: Meet Medical IEC60601-1 & ITE

IEC60950-1, Class I for DT7(C14) or Class II for DT8(C8).

NOTE: (1) All measurements are at nominal input, full load, and +25°C unless otherwise specified.

(2) Load regulation is measured at 115Vac or 230Vac in percentage to indicate the change in output voltage as the load varied from half load to full load (%).

(3) The exact obtainable load regulation depends upon the output cord selected and load current.

(4) Due to requests in market and advances in technology, specifications subject to change without notice.

For the details of safety approval, please consult the factory.
