OPTIONS
Options - Timed Soft-Start firing ramp, with or without peak current control
- Soft-Start firing ramp, specific for infrared lamps
- Timed shut-off ramp
- Limitation of RMS current in load
- 0-90° Delay-Triggering for firing inductive loads in ZC and BF mode
Diagnostic - SCR in short circuit (presence of current with OFF control)
- No voltage
- No current due to open SCR/interrupted load
• Overheat alarm
Current read
