The SZ2E series Thyristor Power Regulator is a product produced by Steinberg (Beijing) Electronics Co., Ltd. It has more than 20 years of successful application experience in the industrial heat treatment industry and is a well-known brand in the domestic industrial heat treatment industry.
This document is the user manual for the Steinberg SZ2E Series Thyristor Power Regulator, designed for industrial heat treatment applications. It details the product's model definition rules and selection criteria for different load types, such as pure resistive and constant resistance loads.
The guide provides comprehensive technical specifications, including input power requirements, signal types (4-20mA, PWM), and protection features like over-temperature and over-current alarms. It includes detailed wiring diagrams for various control modes, LED status definitions, and installation dimensions for different current ratings. This manual is written in Chinese.
| Rated Voltage | 380VAC ±10% |
|---|---|
| Power Frequency | 50Hz ±5% or 60Hz ±5% |
| Manual Control Signal | DC 0~5V |
| Output Method | PWM (Fixed Cycle) or CYC (Variable Cycle) |
| Adjustment Resolution | 20ms (1 cycle) |
| Over-temperature Protection | Stops output above 80°C |
| Operating Temperature | -10℃～+55℃ |
The adjustment resolution is 20ms, which corresponds to one cycle.
The regulator stops output and alarms when the heatsink temperature exceeds 80°C.
