PGU410 power regulator regulates the output voltage by controlling the conduction phase according to the input signal of 4~20mA or manual controller (QN740A101).
About this manual
The PGU410 is a thyristor‑type power supply regulator that controls output voltage by adjusting the conduction phase based on a 4‑20 mA input signal or a manual controller (QN740A‑101). It supports both basic, fast, and constant‑current modes, with selectable input terminals for 100‑110 V or 200‑220 VAC.
The device offers adjustable output range (0‑100 % of input voltage), over‑current protection, heater break detection, and component short/open testing. Settings can be made via front‑panel potentiometers, gradient setters, or manual controllers. It operates in ambient temperatures from –10 °C to +55 °C with humidity up to 96 % non‑condensing. This manual is written in Chinese.
