□ Power supply waveform : Sine wave
□ Voltage fluctuati on tolerance : Max. ±10% of rated voltage
□ Ra ted frequency : 50/60Hz automatic recognition (operation range: 40 – 70Hz)
□ Current capacity : Specify any of 6 types (20A, 30A, 45A, 60A, 80A, 100A)
□ Minimum load current : 0.6A
□ Control output range : Min. 0 – 97% (200V/50Hz power supply)
□ Applicable load : Resistance load or inductive load (transformer primary control: phase control only)
□ Control type : The following types of control can be set.
Px-: Phase control (selected when placing order), phase angle proportional output (P0-),
voltage proportional output (P1-),
current feedback (when optional current detection / alarm output function added) (P2-),
voltage square (electric power) proportional output (P3-)
C1-: Cycle calculation zero voltage switching control
□ Cooling : Self cooling
□ P rotection : 1) Overcurrent protection function (current detection [optional]), output stops at approx. 130% of rated current
2) External rapid fuse (sold separately)
□ Control input : Selection of any one of 3 types
(current 4 – 20mA DC [receiving impedance 100Ω] or voltage 1 – 5V, 0 – 10V DC [input resistance 200kΩ])
Contact 2-position control (on/off control)
□ Standard functions
• Output adjustment function : Ramp setting (higher: 0.1 – 100%, lower: 0.0 – 99.9%)
Slow-up time / slow-down time (0.0 - 99.9 sec)
Input scaling (lower: 0.0 – 20.0%, lower: 80.0 – 100%)
Manual operation (0.0 – 100%)
• External adjustment function : Connecting external adjuster (sold separately) enables ramp setting (higher/lower) and
manual operation adjustment (max. 3)
□ Additional functions (options)
Output current detection / alarm output function: By built-in current sensor (CT)
• Current limit function : Phase control only supported
Limits load current (initial value: 100% of rated current)
0 – 100% of rated current set by external adjuster (current limiter) or 0 – 120% of rated current set by
front panel key operation
• Overcurrent alarm : Overcurrent protection function (output stops at approx. 130% of rated current)
• Hardware error alarm : Detects thyristor device error and outputs alarm.
• Heater break alarm : Detects heater break or deterioration and outputs alarm.
Heater break judgment 0 – 100%
*Heater break alarm judgment precision may be reduced in the case of variable resistance heaters
• Alarm output : 1 point, 1a contact, 240V AC 1A, insulated from system
Power failure, overcurrent, hardware error, heater break selection; alarm contact output;
redundant setting possible
• Data communication function Parameter setting function
(optional) Reads/writes various types of parameters

*Parity: Even
*Stop bits: 1 (fixed)
Writes various setting parameters; reads control input value / output value / alarm
□ External control inp ut function : Manual operation
Standby (output OFF)
