ZG2-42/0.5 silicon rectifierUsage environment:

2.1 Surrounding air temperature: -40 ℃ -+60 ℃

2.2 Relative humidity of air: not exceeding 90% (temperature+25 ℃)

2.3 Atmospheric pressure: 74.8-106kPa (altitude equivalent to below 2500m)

2.4 Vibration frequency: 10-55Hz, acceleration of 2g

Main features of the product:
1. The relay is a heavy-duty DC electromagnetic relay, which uses the principle of "constant gravity" to force the closing contact to disconnect when the coil is powered off.
2. Using silver silver cadmium oxide contacts, it has strong anti adhesion and low contact resistance.
3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and a stopper is installed at the closure between the armature and the iron core to ensure a small air gap in the magnetic circuit, prevent the ferromagnetic parts of the magnetic circuit from magnetizing, and ensure the reliable dropping of the relay.
4. The front coil of the relay is a short-circuit coil enclosed by a diode, without a rectifier unit. The AC power supply is directly connected to the coil and has a certain lightning protection function.
5. The relay contact system consists of ordinary contacts, with four sets of common contacts for dynamic connection and dynamic disconnection conversion.
6. Relays should be used in conjunction with isolation transformers to adjust the system current to ensure reliable operation and release of the relay, and to ensure that the lamp terminal voltage meets the specified adjustment range.
