It is ideal to power resistive actively inductive loads under the mode "ON-OFF" with direct unstabilized current. The above loads require rectified voltage regulation. Carbide silicon heaters and electric furnace heating elements are main load.
They provide for highly reliableand long-term operation under non explosive medium with current conducting dust. The unit maintains high power values under severe conditions.
Functional and structural features are as follows:
The rectifier operates and maintains its parameters at ambient temperatue ranging from plus 5 to plus 50C. Relative humidity upper value is 80% at temperature of 25C.
There are two control modes of the rectifier - remote and local. Remote control is effected either from standard remote control desk or from standard remote control desk from equipment that is ideal for remote control with control signal "0 - 10V" ("4 - 20 mA") and de-energized make contact. Local control is effected from control board of the rectifier.
Output voltage smooth build up is provided.
High reliability and longevity is assured by availability of single SPTA set (with automatic equipment panels).
Operation security is effected by availability of built-up is provided rectifier electronic system ideal for protection against short circuits (internal and external); the rectifier operation more under two-phase load; power thyristors temperature elevation.
An indicator indicates the consumer of rectifier on-state, current overload (mode than 110% of rated value).
Duration of guarantee and service life is up to 10 years;
The rectifiers are cooled with forced air cooling. There is no need in auxiliary adjustment on rectifier operation site. It is suffice to connect supply mains and load.
Manufacture and delivery of rectifiers adjusted for other values of output current and voltage are available according to customer's order.
