- ambient temperature lower value is 263 K (-10C);

- relative humidity upper value is 98% at temperature of 308 K (35C);

- the rectifier should provide for reliable and stable operation after being in inoperative state at temperature ranging from 233 to 333 K (from -40C to +50C).

The rectifier mass (gross) in shipping container, max. 3300 kg.

Overal dimensions (width x depth x height) - 1476 x 1472 x 2304 mm.

Dust-proof version of type

В-ТПП-250-500УХЛ4 IP54

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 reliable and long-tern operation under non explosive medium with current conducting dust. The unit maintains high power values under severe conditions.

The rectifier operates and maintains its parameters at ambient temperature ranging from +5 to +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 another equipment that is ideal for remote control with control signal "0-10V" ("4-20mA") and de-energized make contact. Local control is effected from control board of the rectifier.

Output voltage smooth build up.

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 rectifier electronic system for protection against short circuits (internal and external); the rectifier operation mode the rectifier operation mode under two-phase load; power thyristors temperature elevation.

An indicator indicates the consumer of rectifier on-state, current overload (more 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.
