Transformer Rectifier 3RC10KG

The Transformer Rectifier 3RC10KG provides a high quality output of 27.4 volts dc with a continuous rating of 360A. The Transformer Rectifier comes in a custom steel enclosure that deck mounts. This enclosures can also direct mount for shock levels up to 30g.  Suitable shock mounts must be used for shock levels above 30g.  In addition to these features, this unit also comes with an Ingress Protection level of IP23.

Furthermore, a front hinged door provides easy maintenance access and contains indicating lamps for supply available, anti condensation heater on, output on and the ON/OFF switch. Louvres pressed inwards on the front and sides of the assembly and also a shielded vent on the top of the unit provide for fan assisted cooling during normal operation. Alternatively,  natural convection cooling operates when the Anti Condensation Heaters are on.

Soft Start System

A soft start system makes it possible for the input inrush current to be less than the full load current. The TRU has an input isolation transformer and a 12 pulse thyristor rectifier configured as two fully controlled bridges combined in parallel by an interphase transformer. As a result, a very smooth DC output is produce thus eliminating all harmonics below the 11th from the input current waveform. The input current to the equipment is also close to sinusoidal with a “traditional” lagging power factor dependent on loading and mains voltage.

Electrical Connections

Electrical connections to and from the Transformer Rectifier Unit for supply, heater, remote and sense connections occur on rail-mounted terminals. Provision for the output is by means of M12 bolt connections. The terminals are inside the cubicle.  Access is through a cable gland plate situated on the bottom of the unit. An M10 (x 1.5) external earth stud is provided adjacent to the gland plate, on the bottom of the enclosure.
