The Bosch 1070085723 (PST6250.332-L) is a compact, thyristor-based power unit designed for managing welding transformers. This small device permits operation of circuits with substantial currents and voltages. Operating with three-phase AC voltages between 400 and 600 Volts AC, this unit is highly effective in controlling electrical power. It restricts its maximum duty cycle to 50% with the help of a 2.2 kiloohms de-excitation resistor. This series offers an inbuilt weld timer that functions within a range of 19-30 Volts DC, with a nominal rate of 24 Volts DC. Coming under the air-cooled PST 6250 series, this power unit is housed in an IP 20-enclosed environment and Bosch recommends mounting the product inside an IP 54 industrial switch cabinet for optimal usage. Weighing nearly 27.5 pounds, the unit comes with a thermostatic switch that triggers an alarm when the temperature exceeds 80 degrees Celsius. Indramat USA ships this globally with a one-year warranty.
