Product Description

The VMA 90DR 001-D power supply module features a standard air cooling mechanism. The module has a width of 200mm. This product is capable of operating between 45° and 45° with derated data. The device has a derated power of 1.75W/K when it operates in this power range. It is compatible with a PM VM personality module, an RMD/VM type backplane module and an NAA 90 type line wiring/mains connection module. The unit continues to operate with a 66% power reduction if there is a one-phase mains failure. It comes fitted with a reset button. The module can be sent globally through a reputed shipping agent.

Both the multi-digit displays depict partial alternate flashing if the DC link voltage is over 50V. These displays flash the characters U and 1 alternatively if the output limit of the power supply module is reached during regeneration or supply. The device may encounter overload and fail if it operates with a one-phase failure for a long time. The unit weighs 18kg. It has a peak output of 97kVA. The product also has a regulated DC link voltage of 670VDC and a rated voltage of 400VAC at 50Hz. The unit has a power demand of 3.1A from a 24VDC power supply.

The device features a maximum power loss of 970W inside the switch cabinet. The product can be replaced if needed without switching off the system. The line wiring module must be connected to the left side of the power supply module with a gap of 0.5mm between the two modules. The X99 connector of the unit serves as a RS 232 interface while the X32 connector serves as a logic interface for the NAA module. There should be a minimum clearance of 100mm between the unit and the switch cabinet at the bottom and top. The VMA 90DR 001-D module features a one-year warranty.
