The PF3200-PS12 is a 12V switched power supply (SMPS) that converts an AC voltage of 230V 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. However this power supply is not suitable for inductive loads such as an electric motor or pump.
Output 12V DC – 200A
This stabilized 12V power supply can supply a DC current of up to 200A and has a power output of 3000W.
The output voltage can be adjusted from 0V to 18V, and the current from 0A to 200A.
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 0-200A
In addition to a controllable voltage source, this switched power supply can also be used as a controllable current source. The PF3200-PS12 has a strict current limit, allowing the maximumcurrent to be set with precision.
When set at 13.6V the PF3200-PS12 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 200A the PF3200-PS12 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 (model PF3200-PS12-AI). The current and / or voltage can be regulated by means of an analog voltage (0-5V).
For example, it is possible to control the power supply via a PLC or via external potentiometers. For the latter case DWE has developed a PF-UIC1 which is connected to the switched power supply via a plug cable. This circuit board with potentiometers on it can be mounted at some distance from the power supply, for example on a panel.
Likewise, it is also possible to select different voltages and / or currents via a selector switch, all from one power supply. See datasheet for more information.
