280V DC power supply, 3200W

The PF3200-PS280 is a 280V switched power supply (SMPS) that converts an AC voltage of 230V to 280V DC (stabilized).
The power supplies of the PF series are characterized by high quality, high efficiency and high operational reliability. A big advantage is that both current and voltage are adjustable through onboard trimmers. Therefor this power supply unit can be used as 280V DC power supply, a battery charger or as a LED driver.

Output 280V DC – 10A

This stabilized 280V power supply can supply a DC current of up to 10A and has a power output of 3200W.
The output voltage can be adjusted from 0V to 420V, and the current from 0A to 10A.

The charger/power supply is short-circuit-proof and protected from high temperatures. This power supply has a wide range of applications resulting from its range of input voltages and its ability to adjust the output voltage and current.

Variable current source 0-10A

In addition to a controllable voltage source, this switched power supply can also be used as a controllable current source. The PF3200-PS280 has a strict current limit, allowing the maximumcurrent to be set with precision.

280V Charger

When set at a safe charging voltage the PF3200-PS280 makes an excellant constant voltage charger (IU charging characteristic).
This stabilized power supply can remain connected without risk of overcharging the battery. Because the output current decreases proportionally to the increase in the battery charge.

280V LED driver

Because the current is adjustable from 0 to 10A the PF3200-PS280 can also be used as a LED driver.
The 280V power supply unit is then used as a constant current LED driver.

Remote control

The power supply is also available with a connection for an external control unit (model PF3200-PS280-AI). This allows the current and/or voltage to be controlled by means of an analog voltage (0-5V).
DWE has developed a circuit board that can be plugged in to this connector. This printed circuit board with its potentiometers can be mounted at some distance from the power supply, for example, on a front panel.

If you are interested in this power supply with an external control please contact us and ask for model PF3200-PS280-AI.
