• Input Apparent Power: 32 kVA

• Continuous rated input current: 52.5A; 30min overload input current:71.8A

DC Bus Output Side

• Fixed DC bus voltage: DC 270V ~ 325V

• Rated continuous DC output power:22kW

• Continuous DC output current:70.2A; 30‑minute overload DC output current:95.8A

• Embedded auxiliary output: +24VDC control power for external CNC servo control circuit (core difference vs MR5A model without 24V output)

3. Mechanical & Environmental Spec

• Gross weight: 22.5 kg

• Cooling mode: Forced air cooling with internal built‑in axial fan

• Operation ambient temperature: 0℃ ~ +40℃; storage temperature:‑20℃ ~ +60℃

• Installation: Indoor cabinet mounting only; non‑condensing, free of corrosive gas & conductive dust

4. Core Functional Features

1. Full four‑quadrant regenerative function: Spindle deceleration regenerated energy is fed back to AC grid directly, eliminates external braking resistor, reduces heat loss

2. Multi‑drive parallel DC bus design: Single MR5N2022 converter supplies DC power for multiple parallel CIMR‑M5N spindle inverters on same machine tool

3. Matched pairing: Standard collocation with CIMR‑M5N2022 spindle inverter for 22kW CNC spindle vector drive system, supports spindle positioning/orientation for automatic tool change

4. Complete multi‑protection logic: Overcurrent, overvoltage, undervoltage, input phase loss, overheat, electronic overload protection with fault relay alarm output signal

5. Model Coding Definition

• MR5: VS‑656MR5 regenerative converter series

• N: With built‑in 24VDC auxiliary control power

• 20: 200V input voltage grade

• 22: Nominal supporting 22kW spindle drive power rating
