E859A1 converter (E 859A1, 859A1-E; e859A1, f 859A1, 859A1-e)
E859A1 converter - the measuring instrument is designed for a linear transformation of the active power of three-phase three-wire AC circuits in standard signal outputs direct current.
- Current: 0 to 5 mA;
- Voltage: 80 - 120V.
Power supply: from the measurement circuit.
Overall dimensions 120 × 80 × 120mm.
Weight less than 0.9 kg.
E859A1 converters are made in the standalone unit capable of being fastened on the rails or directly on the panel. Devices made without galvanic connection between the input and output circuits.
E859A1 converters can be used in automatic control and management of power generation facilities and various industries, as well as to monitor the current values of active power.
The operating conditions for the instrument transformers E859A1 served in Table 1.
The time setting of the output signal after a sudden change of input signal from zero to any value of the operating range - less than 0.5 seconds. Warm-up time - no more than 15 minutes.
Unit converter for E859A1 MTBF is at least 50,000 hours. Average lifetime - at least 10 years of age.
