Product Description

The PST6250.177-W is a two-phase AC thyristor power unit by Bosch Rexroth. It belongs to the PST 6250 series and weighs approximately 13 kilograms. This equipment comes with a 24V embedded weld timer, a slot for quality module and an optional programming interface. It has an integrated function control system, and it is water-cooled. The PST6250.177-W offers flexibility and a wide range of applicability. Its voltage rating is 400…600 volts and operating frequency range is between 50 to 60 Hz. The rated current of the PST 6250 series is 200Amps.

The PST6250.177-W can be rear-mounted or vertically-mounted. The PST 6250 thyristor power unit series comes with a fieldbus, parallel or series interface. This equipment is designed to be installed in switchgear cabinets or enclosures; and its class of protection conforms with the indications of IP 20 standards. The PST6250.177-W features a non-linear voltage-dependent resistor (metal-oxide varistors) that protects sensitive components and circuits from a wide range of overvoltage conditions. The maximum working air temperature of this equipment is 55 ^oC, and it can be utilized in welding transformers with a power rating that is up to 250kVA.

This PST6250.177-W comes with a high-end temperature monitor, and its mains supply and electrical connections are linked by box terminals with a maximum conductor cross-section of 95mm². During transportation/storage of this thyristor power unit, the recommended temperature range is between -25 degs C to +70 degs C. Also, the ambient air during operation and storage must be free of acidic substances, damage-inducing objects, metallic vapours and corrosive elements. The maximum installation altitude is 0 – 2000m above sea level, and the acceptable air pressure of this model falls within this range. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
