Solid state relay, 3 phase, SSR-100DA, 100A 3-32V DC to AC

Solid State Relay Features

100A 3-phase solid state relay (SSR) features 3-32V DC input woltage and 24-480V AC output voltage with compact size, high structural strength, good impact resistance, and strong shock resistance. The SSR offers a reliable switching the commercial and industrial loads, such as computer peripheral interface device, printing machine, molding machine, food machine, packaging machine, and so on.

• Built in RC absorption
• Photoelectric isolation
• SCR output
• LED indicator for operation status
• Removable protective cover for safety
• Panel mount
• Zero-crossing switch type

100 Amps 3 Phase SSR Specification

Note:
* When the load current is higher than 10A, a heat sink must be added to the SSR or the SSR should be mounted on a metal base plate with heat dissipation effect, and apply the thermal grease between them. When the load current is higher than is 40A or more, it also needs to add fan cooling or water cooling.

Tips: What are types of (solid state relay) SSR according to SSR trigger form?

Based on trigger form, solid state relay (SSR) can be divided into zero-voltage type (Z) and phase modulation type (P). When the appropriate control signal VIN is applied at the input, the P-type solid state relay turns on immediately. When VIN is undone, solid state relay turns off when the load current drops below the triac's holding current (AC commutation). Z-type solid state relay includes a zero-crossing detection circuit internally. When the input signal VIN is applied, the SSR can be turned on only when the load supply voltage reaches the zero-crossing region, which may cause the maximum delay, half a cycle, of the power supply. Z-type solid state relay has the same turn-off criterion as P-type. But because of its approximate sinusoidal load work current and weak higher harmonic interference, Z-type solid state relay has been widely used.
