■Various optional features■
[Constant current control]
The voltage is automatically adjusted to the set current value.
The constant current accuracy is ±3% or less (constant load) for a power supply fluctuation of ±10% / ±5% or less (constant power supply voltage) for a load fluctuation of 5 times.
Built-in voltage limiter / gate is turned off at peak overcurrent and alarm indicator is turned on.
[Constant voltage control]
The voltage is automatically adjusted to the set voltage value. (It cannot be adjusted above the circuit voltage.)
The constant voltage accuracy is within ±3% (constant load) for a power supply fluctuation of ±10%.
Built-in current limiter/gate turns off at peak overcurrent and alarm indicator lights up.
[Peak overcurrent alarm]
When the gate is turned off due to peak overcurrent, an alarm signal is output.
[Heater break alarm]
Detects heater breakage and outputs an alarm signal.
The number of heaters in parallel can be detected up to 2 for delta load and up to 1 for star load. By
detecting voltage and current, it will not malfunction even if the voltage applied to the heater changes from 0 to 100%.
