# 701 Model
weight : @110 gms. |
Circuit Diagram |
|
|
|
| |
|
| |
- The load Power is Proportional to controller input
- Output to body 4kV-isolation
- Input to Output 2500 vrms isolation
- Heat Sink+Din Rail Mounting (35mm)
- Used for resistive load only
- Do not give DC Voltage at 4-20mA input control of
SSR otherwise input of SSR will fail.
- Phase Line voltage should be in range of 230 VAC
+10 % or 440 vac+10 %
- SSR will not work if heater connnected in star
without neutral.
- Heat sink temperatures should not increase700C
- For dv/dt and transient voltage uses dv/dt
snubber and metal oxide variastor externally.
