Power supply IP-01-MRZS
For the application of a part of MRZS devices that allow power direct current only, or power MRZS from short-circuit currents designed power supply IP-01-MRZS.
Description
Sources of energy for IP-01-MRZS are:
- AC voltage 220 V own needs;
- linear alternating voltage 100 V with voltage measuring transformer;
- alternating currents of measuring current transformers of two phases.
- The output voltage of IP-01-MRZS is 220 V ± 22 V.
- Output power - 33W with powered by circuits voltage or from current circuits over 6 A. With an input current of 4 A - 20 W, at input current 5 A - 25 W.
The range of permissible input voltages and currents at which the technical characteristics of IP-01- are provided MRZS:
- voltage own needs - from 132 to 264;
- voltage from a voltage measuring transformer - from 70 to 150 V;
- current from a measuring current transformer - from 4.0 to 150 A.
- The power consumed by IP-01-MRZS in the selection power take-off is no more than 65 W (79 VA).
