Re:If you need other rated voltage, can be a special order.
Re:
1.Resistive load, including the maximum load inductance300μH;
2. According to extrapolated, it is recommended to do experiments for different situations;
3. After life time, diaelectric strength dropped lower than 100MΩ at 1000VDC;
4. The biggest and current.
Re:A1, A2 as the load; 1, 2 for the coil end; Load and coil has no polarity.
3. The power of drive circuit of the contact coil must be greater than the coil power of the products. Otherwise, the normally usage of high voltage dc contactor will be influenced.
4. The contactor with energy saving board, when connected after 0.15s, the coil starts to switch automatically. Please do not repeat to turn on and turn off. Otherwise, the contactors maybe broken.
5. Working Life: ADH series contactors are high voltage switch. It may lost its switch function when in the breakdown mode. Therefore, please do not use it when the condition is not suitable to the contactors. When the working life is almost there, please to change it in time in order not to flame the parts around. The circuit diagram should be well-designed in order to switch off within 1 second.
6. Internal Gas and Life: ADH series contactors adopt pressurized cabin contact. The cabin is filled with gas. The life of the gas is decided by the cabin temperature of the contact. Therefore, the environment temperature should be ensured between -40 and +85.
7. Please do not use it where the magnetic field is high or near the thermal radiation.
8.To ensure the main power line is closest to the terminal of the contactors. The plain washer, spring washer, nut and screw need to be installed tightly. The incorrect connection order may cause serve overheating and the fusion of the insulating layer.
9. In order not to break the products, the tightening torque of the nuts and screws of the contactors needs to be controlled under the following range.
(1) Terminals: :
M4 screw (ADH series 50A): 2~3N·m;
(2) Mounting Hole:2~3.5N·m.
Please avoid adhering the oil on the terminal.
Please use the following connecting wire. Otherwise, the unusual overheating will be caused:
ADH-50A: nominal area should be above 15mm;
Please do not use the contactor when it is dropped unexpectedly or over-shocked.
1. Small Orders Accepted
2. Quality Approvals
3. Prompt Delivery
4. Packaging
5. Price is good
6. International Approvals
7. Other specification can be customized upon different requirements.
