The training panel contains a digital three-phase relay for detecting earth-faults with isolated and low-resistance earthed, primary distribution networks (ANSI 59N). The relay parameters can be set manually or in conjunction with a PC.
Nominal frequency: 50/60 Hz
Power consumption: 1VA
Thermal load capacity: 520V
Output relay: Switch-on current: 20A Nominal current: 5A Max. contact rating: 1250 VA/DC; 120W/DC, ohmic 500VA/AC; 75W/DC, inductive
LED indicators: "ON" ready "Ue" starting (flashing); for release (permanently on)
Controls: "TEST" button for testing the relay function and the LEDs 2 potentiometers for adjusting the release ranges Ue > coarse and fine adjustments 1 potentiometer for adjusting the release times DIP-switch for: NC, factor for Ue>, selection of the nominal frequency and adjustment of the hysteresis
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 114 x 125mm (HxWxD)
