- The smallest digital power regulator :
26mm width - Single phase / 115mm width – three phase
- Suitable for replacing SSR which has no protecting device. SCR module equipped in Mini is far more durable and reliable than TRIAC in SSR.
- Improved safety through alarming SCR failure which SSR can not detect
- Stable, Reliable and Convenient
Features
Comparison between Mini and SSR
| Content | Mini | SSR | Remark |
|---|---|---|---|
| Load failure alarm | Basically installed | Should attach additional C/T outside or load failure detector | Mini has own C/T inside |
| Over current alarm | Basically installed | None | Output current is more than 100% of its rated current |
| Over temperature alarm | 60℃ Warning, 80℃ Alarm | Mechanical contact | |
| Power module failure alarm | Basically installed | None | |
| Input signal | Select one among 4~20mA / 0~10VDC / SSR | SSR | Select on ordering |
| Alarm point | Basically 2points (Warning 1, Alarm 1) | None | |
| Display | One three color LED displaying operation status and alarm | LED displaying operation status | |
| PCB Power | 10~30VDC | None |
Stability, reliability and convenience
- When power module is failed, electric power to heater is not controlled at full power, which can cause a fire.
- Thus, to detect power module failure is very important to safety directly. Mini equipped with its own CT and CPU secures safety. This is different from SSR which can not detect power module failure.
- In case of SSR, additional device as CT or load failure detector should be attached to detect load failure. But Mini has its own CT, so no need to install any other device which can save labor cost and remove unnecessary wiring job. Eventually, it maximizes convenience.
- Control accuracy is enhanced with compensation algorithm.
- Long period of experience in digital power regulator allows Mini to satisfy stability and reliability.
