JZXC-20000 type rectifier relay

Product Features

The JZXC-20000 rectifier relay is used as a buck-boost control relay in the power supply screen; as a signal channel and track power supervision relay; and a conversion relay between the main screen and the backup screen.

Applicable environment

a) Ambient temperature: -40℃~+60℃;

b) Relative humidity: not more than 90% (temperature +25°C);

c) Air pressure: not less than 70kPa (equivalent to below 3000m above sea level);

d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm;

e) Working position: horizontal;

f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken.

Features

1. The relay is an AC 220V heavy elastic rectifier electromagnetic relay, which adopts the principle of "constant gravity" to force the moving and closing contacts to open when the coil is de-energized.

2. It adopts silver-silver oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance.

3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and a stop piece is installed at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the magnetization of the ferromagnetic parts of the magnetic circuit, and ensure the reliable fall of the relay.

4. The relay consists of two parts: a rectifier circuit and a non-polar relay. The rectifier circuit is a bridge rectifier circuit composed of four 1N4007 silicon rectifier diodes. The input of the rectifier is alternating current, and the rectified current output to the coil is direct current.

5. The relay contact system is composed of common contacts, with six groups of common contacts for switching on and off.
