Three-phase solid state relay assemblies (non-contact switch)



The product consists of a solid-state relays, radiator, fan, temperature control opening and turn on and off the terminal and other components, greatly simplifying the customer’s installation process. In many work situations frequently switch, can replace AC contactor use, long life and easy maintenance. 2500VAC optical isolation, the load current of 60A-1000A, load the power supply 48-480VAC. Cooling fan with temperature control switch (45 ℃ turn), to ensure that the life of the fan; and having over-temperature protection, when the temperature exceeds SSR radiating portion 75 ℃, automatic shutdown input control signal, to protect the SSR at high temperature may decrease the overall performance cause damage.

Specifications Model table:

Note: The table listed resistive bar to use the power of a star connection method for the calculation of the standard, other connection separately calculate load power.

Typical Application:
  

The maximum load current and ambient temperature characteristics


Semiconductor interference overvoltage surge protection components:

YRC1 series, YRC2 Series Size (mm): 29 × 12.6 × 20
YRC1, YRC2 has good noise suppression, and absorb energy spikes, blocking ** available, overvoltage YRC1≤850VDC, YRC2≤1100VDC;
Controllable ends YRC1 be connected across the power supply 220VAC or 380VAC resistive load, ** and load output terminal, such as a single-phase solid state relay.
YRC2 can be connected across the two ends of the SCR 380VAC load, as well as between the load output of the three-phase solid state relay.
