Single phase SSR voltage regulator
For the 25A model:
Typenr | Input | Output |
---|---|---|
SSR-1VD25A | 0-10VDC | 0-250VAC 25A |
SSR-1VF25A | 0-5VDC | 0-250VAC 25A |
SSR-1LA25A | 4-20mA | 0-250VAC 25A |
Specification
- Max input current: 12mA
- Operation temperature: -20°C to 80°C
- Max off-state leakage current: 2mA
- Dielectric strength: 2500V
- Certificates: CE, ROHS
- Load current choice: 10A, 25A, 40A, 50A, 60A, 80A, 100A, 120A
- Weight: 100g
Functions
- Only suitable for resistive load.
- Not applicable to inductive load and capacitive load, such as transformers, motors, ventilators, etc.
- Choose your resistive load to not go over 70% of the model load: If you have a 70A resistive load, choose the 100A model.
- Use a heat sink for the larger loads. The module has a flat metal underside, meant to be mounted on a heat sink with thermal paste.
