CIMR-MRXN2015
Description
1. Basic Product Info
MRX: Compact optimized version of standard MR5 regenerative series;
N: Equipped with built-in internal DC24V auxiliary control power supply for CNC peripheral control circuit;
20 = 200V AC input class; 15 = nominal 15kW rated supporting capacity
Application: CNC lathe, machining center shared DC bus system, supply DC power for multiple CIMR‑M5N spindle inverters; four-quadrant energy regeneration back to grid to cancel brake resistor
Product Status: Discontinued original production; only new surplus stock & refurbished replacement available for old machine maintenance

3. Mechanical & Environmental Data
Net weight:10.5kg
Cooling mode: Built-in axial fan forced air cooling
Operation ambient temperature:0℃~+40℃; storage temperature:-20℃~+60℃
Installation: Indoor cabinet wall-mounted; non-condensing, free of corrosive gas and conductive dust, ambient humidity 5~95%RH non-dewing
4. Core Functions
Full grid regeneration: Spindle braking regenerated power fed back directly to AC mains, eliminate external braking resistance, reduce cabinet heat generation
Multi-drive parallel DC bus: Single MRXN2015 can supply several parallel M5N spindle inverters on same CNC equipment
Standard matching: Paired with CIMR‑M5N2015 15kW spindle inverter for full vector spindle control, support spindle orientation for auto tool change
Complete protection: Overcurrent, overvoltage, undervoltage, input phase loss, heatsink overheat, electronic overload protection with fault relay contact alarm output for CNC linkage stop
