IA-3, IA-4 SOFT STARTERS
Functions of IA-3, IA-4:
- controlling electric drives of regulating valves;
- softly starting an electric motor;
- electrodynamically braking an electric motor.
Technical characteristics of IA-3:
- capacity of controlled electric motors – from 3 to 15 kW;
- range of operating ambient air temperatures – from +5 to +75 °С;
- DU-О and DU-Z control commands are characterized by direct or pulsating voltage 24 V;
- power supply of IA-3 – three-phase voltage 220/380 V.
Technical characteristics of IA-4:
- capacity of controlled electric motors – from 0.06 to 3.5 kW;
- range of operating ambient air temperatures – from +5 to +50 °С;
- DU-О and DU-Z control commands are characterized by a range of direct or pulsating voltage from 18 to 34 V;
- power supply of IA-4 – three-phase voltage 220/380 V.
- structural design (a remote device for wall or panel mounting) assures ease of installation and maintenance;
- possibility of implementation of different variants of actuator control:
- from local regulators;
- from controllers of instrumentation and control systems;
- from a console of a process operator (manually);
- use of several modes of operation:
- intermittent with frequency up to 630 activations per an hour.
