HVR02.2-W010N

Regulated DC bus ensures that downstream drives see a stable voltage even if mains fluctuates within ±10%, which improves drive responsiveness and prevents performance drop during undervoltages. It also helps reduce harmonic distortion and ripple that could degrade sensitive control electronics.

An 80 kWs regen capacity means the unit can absorb fairly large amounts of braking energy before exceeding its internal limits; so external braking resistors may be reduced, but one must still verify that DC-bus capacitors, chokes, and downstream circuits can handle the energy pulses. In high-dynamic applications (lots of stopping/starting) the energy absorption time and the cooling effect during regeneration must be considered.

The peak rating (30 kW) is allowed only for very brief periods (e.g. ~0.3 seconds) to handle acceleration or sudden load increases; it isn’t meant for sustained operation. Continuous load should remain within the 10 kW rating to ensure reliability and to avoid overheating or stressing power electronics.

Yes—multiple Indramat drive modules can be powered from one DC bus supplied by this unit, as long as their combined steady and peak loads do not exceed the HVR’s capacity. Wiring length, interconnection impedance, and potential voltage drop must be managed (twisted or shielded cables, adequate cross-section) to avoid bus voltage sag or instability.

It meets CE marking, UL508C listing, and performs insulation and dielectric strength tests per EN50178; safe separation between control and high-voltage parts is enforced. This means the unit can be deployed in industrial environments with legal compliance, but you must follow the environmental limits (temperature, altitude, humidity, mounting, vibration) specified in documentation.
