Electro Servo Unit
Capacity controlled by input signal
– Electro Servo Unit is capable of combining with all kinds of pumps.
Features & Cautions
- Auto-control by the input signal. (Diversity)
Dong-il Servo unit is able to control discharge volum of metering pump automatically by the input signal of flow, pH, turbidity etc. (DC 4~20mA/~1-+5V)
- The whole type Servo unit
Dong-il Servo unit is sealed off by the whole type protective cap with automatic controlling circuit and servo motor on the pump. Accordingly, it’s showing maximized function at indoor and outdoor.
- Various controlling mode (Fixed Quantity)
Dong-il Servo unit is possible to control widely with invertor. Therefore it’s not only transfer of fixed quantity but also most suitable at violent site of variation of operating condition.
- Protective function for servo motor(Durability)
Dong-il Servo unit has been equipped clutch lever separately. So it gives protection of damages from the servo motor when have continuous operation of Auto/Manual.
- Handiness of system (Simplicity)
Dong-il Servo unit is possible to do simpley instrumentation work because feedback and the other wiring are not necessary.
- Above specifications are that should be changeable due to improvement etc without any notice.
