Product Description:
The TVM 1.2-050-W1-220 is a power supply module manufactured by Bosch Rexroth Indramat as part of the TVM Power Supply Modules series. Installed inside drive cabinets, it converts factory mains into a stabilized DC link for Indramat servo drives and also supplies 24 V control electronics. By combining rectification, energy storage, and internal discharge circuitry, the unit provides the regulated power backbone required for coordinated industrial automation. This arrangement lets one module supply a common power source for the connected drive group inside the cabinet.
The module accepts a primary input of AC 220 V and delivers a continuous output of 25 A on its DC bus, which is held at DC 300 V. During acceleration peaks, it can furnish up to 150 A for brief periods, allowing connected axes to overcome inertial loads without excessive bus sag. Its total power capability is rated at 15 kW, which indicates the power available to the connected drives from the link. The stabilized DC bus supports consistent inverter operation across multiple connected axes. Internal cooling is handled by a built-in blower that channels air through the heat sink. Auxiliary taps at AC 230/400 V energize cabinet peripherals, and a continuous bleeder dissipates 0.30 kW to absorb regenerated energy with a feedback capacity of 14 kWs. Protection class IP10 indicates installation inside an enclosed cabinet, while configuration code 2 and series index 1 indicate the module version within the series.
A 24 V supply rated at 4 A supports PLC I/O and relay coils, keeping control logic active during main bus discharge. That control supply helps maintain logic operation long enough for orderly shutdown behavior after mains removal. The unit is specified for operation up to 1000 m above sea level without derating, and its thermal design limits internal power loss to 550 W. The module weighs 15 kg. Its type current is 50 A for system sizing.
