120V to 12V DC power supply, 720W
The PF750-PS12-U is a 12V switched power supply (SMPS) that converts an AC voltage of 120V to 12V 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 12V DC power supply, a battery charger or as a LED driver.
Output 12V DC – 40A
This stabilized 12V power supply can supply a DC current of up to 40A and has a power output of 720W.
The output voltage can be adjusted from 0V to 18V, and the current from 0A to 40A.
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 0-40A
In addition to a controllable voltage source, this switched power supply can also be used as a controllable current source. The PF750-PS12-U has a strict current limit, allowing the maximumcurrent to be set with precision.
When set at 13.6V the PF750-PS12-U 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.
12V LED driver
Because the current is adjustable from 0 to 40A the PF750-PS12-U can also be used as a LED driver.
The 12V power supply unit is then used as a constant current LED driver.
The power supply is also available with a connection for an external control unit (model PF750-PS12-U-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 PF750-PS12-U-AI.
