விவரம்
- Down-opened Panel is easy for fuse replacement.
- Automatic detection with multi-LED display for power out-of-phase, SCR over-heat, and fuse burn-down with one set of alarm dry contact output.
- Independent adjustment of Max and BIAS, easy adjustment for the VR of Max & SFS on the front panel.
- The auxiliary powers (AC1 & AC2) are independently controlled for all models.
- Build-in buffering output adjustment (SFS VR) with adjustable range 1~22 seconds. (Only for the phase control)
- In case of 0.5Hz sudden power losses, system output can be switched off immediately.
- Once the power is restored, the system will buffer the output to prevent the voltage surge for fuse burn-down.
- One main power design for 200~480VAC and automatic power frequency detection for 50~60Hz.
- In cases of SCR over-heat or fuse burn-down, the system output is stopped immediately. Once the malfunction is eliminated and power is restored, the system will buffer the output to prevent the fuse burn-down.
- Selectable signal 4~20mA, 1~5VDC, 2~10VDC, 0~20mA, 0~5VDC, 0~10VDC and dry contact points. Triggering circuit and the main board are designed separately to avoid the main board damage when main circuit malfunction.
- Safety top & bottom shielding covers are easy for wiring, using European detachable control signal connector
for easy replacement without re-wiring installation.
