Product Details

The Easy Front Key Setting interface on the 7-segment LED display provides a clear and intuitive way to monitor and adjust input and output values, along with various parameters. This advanced system features a Slow-Up and Slow-Down function to smoothly transition between settings, enhancing user control. The universal power supply supports a wide voltage range of 100 to 240V AC, and the automatic frequency discerning function accommodates both 50 and 60Hz, ensuring reliable operation in diverse environments. Data communication is available as an option, facilitating seamless integration with other systems. For added functionality, it includes an optional current detection and alarm output feature, which ensures timely notifications for any deviations.

Current capacityAny one of 6 types (20, 30, 45, 60, 80, 100A)
Minimum load current0.6A
Control output range 0–97% or more (when power supply voltage is 200V/50Hz)
Applicable loadResistive load/inductive load (transformer primary control: Phase control only)
Control systemThe following control systems can be set:
 Px–: Phase control system: Phase angle proportional output (P0–)
           Voltage proportional output (P1–)
           Current feedback (current detection/alarm output function option) (P2–)
           Square of voltage (power) proportional output (P3–)
 C1–: Cycle calculation zero voltage switching control system
CoolingSelf cooling
Protection1) Overcurrent protection function (current detection option):
Stops output when detecting approx. 130% of rated current.
 2) External rapid fuse (sold separately)

Standard functions
Output adjuster functionRamp setting (higher limit: 0.1–100%, lower limit: 0.0–99.9%)
Slow-up time/slow-down time (0.0–99.9 sec.)
Input scaling (lower limit: 0.0–20.0%, higher limit: 80.0–100%)
Manual operation (0.0–100%)
External adjustment functionRamp setting (higher limit/lower limit) and manual operation adjustment are possible by connecting external adjuster (sold separately) (up to 3 external adjusters can be used).
Additional functions (optional)
Output current detectionBuilt-in current transformer [CT]
Current limit functionPhase control system is only supported.
          Limits load current (initial value: 100% of rated current)
Current limit value can be set within the rated current range of 0–100% by external adjuster (current limit adjuster), or it can be set within the rated current range of 0–120% by front panel operation.
Overcurrent alarmOvercurrent protection function (stops output at approx. 130% of rated current.)
Hardware error alarmAlarm is output when thyristor elements error is detected.
Heater break alarmAlarm is output when heater break is detected.
Heater break judgment: 0–100%
*When using changing resistance heater, judgment accuracy of heater break alarm may decrease.
Alarm output1 point, 1a contact, 240V AC, 1A, insulate from system.
       Select from power failure, overcurrent, hardware error, or heater break
       Alarm contact output in response to occurrence of error: duplicate setting is possible.
