The R911190000 (HVE02.2-W018N) is an HVE series power supply unit designed for supplying electricity to HDS and HDD drive controllers. It converts 3-phase input AC voltage (380 to 480 V AC) into an unregulated DC bus voltage (530 to 670 V) for the connected drive system. The device provides a control voltage output of 300 W, with a maximum power draw of 500 VA and a rated power of 18 kW. Operating within a temperature range of 5 to 45 degrees Celsius, it uses internal air cooling via a built-in blower and must be mounted vertically inside a control cabinet. The unit supports motors up to 60 kW mechanical power, integrates supervisory functions, and includes protection class IP10. In generator mode, regenerated energy is dissipated through the bleeder resistor, and a CD bus choke (GLD) may be used for prime power adjustment.

Frequently Asked Questions

What cooling and clearance considerations are needed for reliable operation in a control cabinet?

Although it has an internal blower, the HVE02.2-W018N’s bleeder resistor and other heat-dissipating components require at least ~300 mm above and ~40 mm to the front/sides for airflow. Without adequate clearance or supplemental cabinet ventilation or cooling units, thermal accumulation can reduce life or trigger thermal shutdown.

How does the choice of HVE (unregulated) vs HVR (regulated) series affect regeneration and energy recovery in a robotics or CNC setup?

The HVE series dissipates regenerated energy as heat via a bleeder resistor, whereas HVR units feed it back into the mains, improving energy efficiency. For applications with frequent braking or dynamic motion, using HVR or externally handling regenerated energy can reduce energy loss and cooling burdens.

How many drive axes (servo modules) can be supplied by one HVE02.2-W018N without overloading its control voltage output (300 W)?

The control voltage output must power all auxiliary circuits (sensors, relays, diagnostics) in addition to the drive control electronics. If many axes are used, the sum of their control currents must stay under ~300 W; exceeding that may require a separate auxiliary supply or limiting the number of axes to ensure safe margin.

In what sense is the “continuous bleeder power” relevant, and how should it be considered in system design?

The continuous bleeder power indicates how much regenerated energy the unit can dissipate continuously (as heat) without damage. If your system experiences frequent braking or energy regeneration beyond that capacity, the cabinet will heat up quickly and you may need external heat sinks, ventilation, or even switch to a module/regulation mode that feeds back to mains (i.e. HVR).

What are the power loss factors (base losses vs load-dependent losses) and how do they affect efficiency and cooling demands?

The unit has fixed base (idle) losses plus losses proportional to output load; at full output the load-dependent losses increase. In practice, running continuously near full load increases heat dissipation substantially, which raises cooling demands; for better efficiency, operating at moderate load (e.g. 70-80%) often keeps losses and cooling manageable.
