RODUCT DESCRIPTION

The FPS300 is an industrial grade power supply for

a 1-phase mains system that is incorporated into a

rugged wall-mount housing with an IP65 and IP67

degree of protection.

It provides 1 stabilised output that is galvanically

insulated from the input. The negative terminal of

the output is permanently connected to PE within the

unit.

The most outstanding features of the FPS series are

compact size, wide operating temperature range,

extremely low input inrush current and very high

efficiencies, which are achieved through various

design topologies. The large output capacitors can

absorb and store regenerative energy from braking

motors.

High immunity to transients and power surges as well

as low electromagnetic emissions and an international

approval package make the use in nearly every

application possible.

All parameters are specified at 24 V, 300 W, 230 Vac, 25 °C ambient and after a 5 minutes run-in time unless otherwise noted.
