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.
