    Product Datasheet: Carlo Gavazzi RGC1P48AA42ET Solid State Relay

  • Product Description:

    The Carlo Gavazzi RGC1P48AA42ET is a compact 35mm proportional output solid state relay capable of switching 43 amps at line voltages between 190Vac and 550Vac in a 40°C ambient. Known for Quality and reliability, the Carlo Gavazzi RGC1P48AA42ET proportional output solid state relay incorporates internal overvoltage protection and utilizes rugged back-to-back SCRs to switch power to/from electrical loads, making them the ideal switching solution in residential, commercial or harsh industrial environments.

     

    The input of the RGC1P48AA42ET accepts a 4-20mA analog input signal. The output of the solid state relay will apply a percentage of AC power to the load in direct proportion to the analog input signal applied. The RGC1P48AA42ET does not require an external supply to power the analog control circuit.

     

    The RGC1P48AA42ET has seven different operating modes, which is selectable on the faceplate of the solid state relay:

     

    Mode 1: Phase-Angle Switching

    The Phase angle switching mode works in accordance with the phase angle control principle. The power delivered to the load by the solid state relay is controlled by the firing of the thyristors over each half mains cycle. The firing angle depends on the input signal level that determines the output power to be delivered to the load.

     

    Mode 2: 1x Full Cycle Switching

    In Full cycle switching modes, only full cycles are being switched by the solid state relay. Switching at zero voltage reduces EMC interference as compared to phase angle switching (mode 1). The ON full cycles are distributed over a specific time base. This enables faster and more accurate control of the load in addition to extending the heater lifetime. This mode is suitable for use only with resistive loads.

     

    Mode 2 offers the lowest resolution for full cycle switching, i.e., 1 full cycle. At 50% output power demand the solid state relay will switch ON the load for 1 full cycle and OFF for 1 full cycle in a repeated pattern. Below 50% output power demand, the non-firing period increases but the firing period remains fixed at 1 full cycle. Over 50% output power demand, the firing period increases but the non-firing period remains fixed at 1 full cycle.

     

    Therefore, at 25% output power demand, the non-firing period gets longer and the solid state relay will switch ON the load for 1 full cycle and OFF for 3 full cycles in a repeated pattern. At 75% output power demand, the firing period is longer and the solid state relay will switch ON the load for 3 full cycles and OFF for 1 full cycle in a repeated pattern. At 100% output power demand, the solid state relay switches the load fully ON.

     

    Mode 3 and Mode 4: 4x and 16x Full Cycle Switching

    In mode 3 the minimum resolution is 4 full cycles. At 50% output power demand the solid state relay will switch ON the load for 4 full cycles and OFF for 4 full cycles in a repeated pattern. Below 50% output power demand, the non-firing period increases but the firing period remains fixed at 4 full cycles. Over 50% output power demand, the firing period increases but the non-firing period remains fixed at 4 full cycles.

     

    In mode 4 the minimum resolution is 16 full cycles. At 50% output power demand the solid state relay will switch ON the load for 16 full cycles and OFF for 16 full cycles in a repeated pattern. Below 50% output power demand, the non-firing period increase but the firing period remains fixed at 16 full cycles. Over 50% output power demand the firing period increases but the non-firing period remains fixed at 16 full cycles.

     

    Mode 5: Advanced Full Cycle (AFC) Switching

    This switching mode is based on the principle of distributed full cycle explained above with the difference that the resolution for firing and nonfiring periods is changed to a half mains cycle. This mode is intended for use with short / medium wave infrared heaters. The purpose of the half cycle non-firing time is to reduce the annoying visual flickering of such lamp loads. Below 50% output power demand, the solid state relay switches ON the load in half cycle periods. The non-firing periods are full cycles. Above 50% output power demand, the solid state relay switches ON the load in full cycle periods but the non-firing periods are half cycles.

     

    Soft Start Modes:

    Soft starting is utilized to reduce the start-up current of loads having a high cold to hot resistance ratio such as short-wave infrared heaters. The thyristor firing angle is gradually increased over a time period of maximum 5 seconds (settable through an accessible potentiometer) in order to apply the voltage (and current) to the load smoothly. Soft starting is performed on the first power up and in cases of non firing periods exceeding 5 seconds. If soft start is stopped before soft start completion, it is assumed that a start was performed and the non-firing period count start as soon as the soft start is stopped.

     

    Mode 6: Soft Start + Mode 4 (16x Full-Cycle Switching)

    This switching mode works on the principle of switching mode 4 (16x full cycles) but soft starting is performed on power up or in case of the non firing periods exceeding 5 seconds. After the soft start is completed, full cycles (with a resolution of 16 full cycles) are delivered to the load according to the input signal, based on MODE 4 switching principle.

     

    Mode 7: Soft Start + Mode 5 (Advanced Full-Cycle (AFC) Switching)

    This switching mode works on the principle of the advanced full cycle (mode 5) but soft starting is performed on power up or in case of the non-firing periods exceeding 5 seconds. After the soft start is completed, output power is delivered to the load according to the input signal, based on Mode 5 switching principle.
