Overview
The PSW Universal signal converter is used for connecting modern high-efficiency
pumps to controllers without a corresponding output. Due to its many adjustment
possibilities, almost any pump can be connected.
• No controller replacement required
• For solar and heating pumps
• Flexible in- and outputs: PWM, 0-10 V, 0-20 mA, 4-20 mA
• Inversion of the output signal possible
• Also usable as a PWM repeater
The PSW Universal pump signal converter converts the 230 V signal of the con-
troller to which a standard pump had previously been connected, into a signal that
enables speed control of a HE pump. 1 HE pump per signal converter connectable.
