W.E.St. PAM-140-P -A-10101, -I-1010, PAM-190-P, PAM-193-P, PAM-199-P Universal Mobile Power Amplifier Technical Documentation

Below you will find brief information for PAM-140-P PAM-140-P-A-10101, PAM-140-P PAM-140-P-I-1010, PAM-190-P PAM-190-P. This power amplifier is used to control proportional valves with one solenoid. The compact solution is implemented in an inexpensive IP-65 housing. A typical input signal of 0… 10 V (optional 4... 20 mA) can be used. The output current is closed loop controlled and therefore independent from the supply voltage and a varying solenoid resistance.

Frequently asked questions

This power amplifier is designed to control proportional valves with one solenoid.

The typical input signal range is 0…10 V, but it can also be configured to accept 4…20 mA signals.

The output current is closed loop controlled, meaning it is independent of the supply voltage and a varying solenoid resistance.

The power amplifier can deliver a maximum of 1 A or 2.5 A, depending on the configuration.

You can parameterize it via the PC interface and the ULA-310 adapter or internally via the UP and DOWN buttons.
