REP 37-E-220 is a standard series digital/electronic potentiometer with dimensions of 37*72mm and a 220V input voltage. It is an easy-to-use device that can increase or decrease the output analog value (DC 0-10 volts) through digital keys. The output voltage value can be proportionalized to the machine's condition with a multiplier value if desired. This product is typically used for speed control device speed adjustment, and it has parameters for setting the output value as open or closed and ramp times.

This series is an old model that we only keep for backup purposes. Similar products are recommended below for your new projects.

The output voltage limits can be set to obtain low and high-speed levels via the device. The device can remember the last point it stopped at during a power outage and continue from there, or it can be started from zero with a ramp if desired. The energy supply voltage of the device may vary from model to model. Products sold domestically are manufactured in 12VDC, 24VDC, and 220VAC options.

The REP electronic potentiometer and analog control device are designed for industrial machine environments. It is galvanically isolated to operate alongside potential parasite-emitting products such as power supplies, frequency inverters, servo drivers, etc., on the same panel.

Note: This device cannot be used as an adjustable power supply. Its production purpose is entirely for reference setting of speed control devices. Do not connect any other receiver or load to the output.

Editor's Note: Dear friends, the REP series has been discontinued. It has been replaced by the DPT series potentiometers. Unfortunately, REP series had some problems, such as the inconvenient keypad, known issues on the casing, and low resolution. I recommend that you prefer the new series, which has solved all of these problems and has a higher resolution with an additional new processor. (Personal opinion)
