JPC 100/200/300
Freeze protection heating wire starting current controller
Details
The JPC series are starting current controllers designed for freeze protection applications. They can be installed into cabinets or incorporated as part of junction box equipment.
Fault contact output and alarm system
– Alarm occurs when short-circuiting the earth leakage breaker (ELB).
– Alarm in case of temperature sensor short-circuit or connection error
Security-enhanced setting value change method – Only authorized administrator can change setting
Automatic switching to Auto mode, Manual mode
After start-up, switch to the automatic mode by yourself to prevent winter frost accident
Initial starting current control: Reduces the construction cost by 30% by doubling the heater circuit length
Extending the system to the central monitoring monitor (optional)
Connected to the central monitoring monitor in the management room to check the operation status of hot wire at a glance
