Digital power control manufacturer
- Designed to select any control method suitable for all kinds of loads and circumstances.
- For TES product, one three phase product or three single phase products can be selected on ordering to maximize space.
- Possible to read and write through PSD(PARA SMART DISPLAY) or communication function. And with just one PSD, every parameter and alarm can be selected for multiple SES/TES.
Feature
Comprehensive control
- Designed to use any kind of control method(Zero-crossing, phase-angle, current feedback, voltage feedback, power feedback) suitable for different type of load.
- Customer can select control method any time and at any place.
Powerful communication function
- RS-485 communication is basically installed and read and write is possible through communication.
- Maximum 128units can be connected.
- Maximum 115,2000bps is allowed for MODBUS(RTU) protocol.
Smart partial load failure detect
- With simple switch on/off, partial load failure can be easily set and precisely detected.
- Partial load failure detect is to find out load failure partially on parallel loads.
- Auto-tuning function for partial load failure is to obtain each feature of different load for precise detection.
Alarm history
- Last 6 alarms are saved to check out type of alarm easily.
- Even main power is cut off by alarm function, alarm history is saved for better maintenance and user’s convenience.
Convenient parameter setting by PSD
- All parameters and alarms are selected by PSD or RS-485 communication.
- Through selecting parameters and alarms, the usage can be optimized at different circumstances.
- Multiple SES/TES products under the same condition and same rated current, all parameters and alarms can be selected with only one PSD using COPY&PASTE function. This is to save time and money. And if you connect PSD to any of SES/TES product, you can check out the status of product immediately.
Ordering Code
| ① Model | SES : Single phase , TES : Three phase |
| ② Rated voltage | 1 : 110V / 2 : 220V / 3 : 380V / 4 : 440V |
| ③ Rated current | Single phase : 25A ~ 130A Three phaes : 25A ~ 200A |
| ④ Control method | Note 1)PA : Standard phase-angle / PI – Current feedback / PV – Voltage feedback / PW – Power feedback / ZC – Zero-crossing |
| ⑤ Input signal | I : 4~20mA, V : 0~10V |
| ⑥ Cooling fan | DCFN : DC Fan (Alarming when out of order) ACFN : AC Fan (No alarming when out of order) Auxiliary AC 220V power needed SES : DCFN is basically installed more than 70A products TES : DCFN is basically installed all three phase products |
| ⑦ Wiring | Note 2) TES 1P3L : Three single phase 3P3L : One three phase SES : No wiring option |
| ⑧ PSD (option) | PSD : Need PSD (Option) NONE : Not need PSD |
Note 1) Control method is to select factory default and can be changed to user’s need.
Note 2) Wiring is needed just for TES product. This wiring can not be changed arbitrarily.
