Item No.: CO3301-4G

Power and Reverse power relay

The training panel contains a single-phase, directional power relay (ANSI 32 and 37). The unit also includes software for self-testing. The relay parameters are set either manually or using a PC.

  • Nominal voltage: 100V, 110V, 230V, 400V

  • Nominal frequency: 35-78Hz

  • Power consumption:
    - voltage circuit: 1VA
    - current circuit: 0.075 VA at I
    N = 1A, 0.1VA at In= 5A

  • Working range of power detection:
    - voltage circuit: 40....130% U
    N
    - current circuit: 0...120% IN

  • Thermal load capacity:
    - voltage circuit: 520V/AC
    - current circuit: 4x I
    N

  • Output relay:
    Switch-on current: 20A
    Nominal current: 5A
    Max. contact rating:
    1250 VA/DC; 120W/DC, ohmic
    500VA/AC; 75W/DC, inductive

  • Adjustment ranges:
    PR > 1.... 30% P
    N
    P> 1....120% P
    N
    tPr 0....10s/0...100s
    tP 0....10s/0...100s

  • LED indicators:
    - "ON" = Ready
    - P< and Pr> Starting (flashing)
    - P> and Pr> Starting (permanently on)

  • Controls:
    - "TEST" pushbutton = initiate self-test
    - 6 potentiometers for adjusting trip range and switch off times
    - 8 DIP switches for defining nominal values

  • Inputs/outputs: 4mm safety sockets

  • The integrated interface RS 485 is suitable for setting the relay parameters. It is also possible to store and transmit measured relay values to and from the PC. Optical signal transmission guarantees galvanic isolation.

  • Indicators ot the interface:
    1. LED green = operation indicator
    2. LEDs green = data transfer

  • Dimensions: 297 x 228 x 125mm (HxWxD)

  • Weight: 1.0 kg
