Features

?

1. The bidirectional thyristor output adopts a proportional zero-crossing control method, which turns the thyristor on or off when the AC zero crosses.

2. The input end and output end are optically isolated, which is conducive to the control of weak current to strong current.

3. The isolation voltage between the input terminal and the output terminal is 2500V;

4. 100% load current aging test, passed European CE certification, international ISO9000 certification, and domestic 3C certification.

5. Equipped with complete protective cover

Product application

?

The ZG1NC series solid-state voltage regulator adopts a flame-retardant engineering plastic shell, epoxy resin potting, and threaded terminal wiring. It has high structural strength, impact resistance, and strong vibration resistance. The input end drive current is small and can be easily connected to computer terminals and various A digital program-controlled circuit interface, widely used in petrochemical equipment, food machinery, packaging machinery, textile machinery, CNC machine tools, plastic machinery, fitness equipment, entertainment facilities and other automation control fields.

It is especially suitable for use in harsh environments such as corrosion, moisture, dust-proof, and explosion-proof requirements, and in situations where frequent switching is required. It is an updated replacement product for AC contactors.

Safety precautions

1. When the load current is higher than 5A, a radiator must be used or installed on a metal base plate with corresponding heat dissipation effect. Thermal silicone grease should be applied between the solid state relay heat dissipation base plate and the mounting surface. Above 40A, a fan should be used for forced cooling or water cooling.

2. When used with inductive loads, high transient voltages and surge currents are applied to the output end, which may cause the solid-state relay to mislead or be damaged. It is usually necessary to connect a voltage control device with a specific clamping voltage to the output end, such as a bidirectional relay. Zener diode or varistor (MOV). It is recommended that the varistor be 1.6-1.9 times the rated voltage.

3. When controlling a smaller load current load close to the minimum load current, a virtual load resistor must be connected in parallel to the load to reduce the output leakage current and produce a higher residual voltage on the load.

4. In order to prevent the temperature rise of solid-state relays from exceeding the allowable value, the heat dissipation effect and installation location should be considered when designing and applying. When two or more solid-state relays are installed side by side, appropriate spacing should be left.

5. The output terminals of multiple solid-state relays must not be used in parallel in an attempt to increase the output current. However, the output terminals can be used in series to accommodate higher operating voltages.

6. When using multiple solid-state relays to share a control power supply, the input terminals can be used in series or in parallel.

7. Please use this piece with caution for capacitive loads. Please choose a solid-state relay dedicated for capacitive loads.
