KHACHIMO 2900W Rectifier Module

The KHACHIMO GPR4850DR03 is a 53.5V 2900W communication power rectifier module built for telecom and industrial infrastructure. It delivers high-density DC power in a hot-swap form factor suited to 4850 platform shelves. Buyers needing ATX desktop connectors or consumer GPU cables will not find them here.

Sustained 2900W Output Stability

Designed for continuous 2900W load in carrier-grade environments, the module maintains regulated 53.5V output through active current sharing and thermal management. Efficiency stays consistent across the operating range without the derating seen in short-burst designs. Systems requiring redundancy beyond 3 modules must scale the shelf accordingly.

Questions about this item

How much heat does the 2900W rectifier module produce when running continuously?

At full 2900W output the module dissipates the difference between input and output power as heat; ensure the telecom shelf provides forced-air cooling rated for high-density rectifiers.

What must the rack or shelf already provide for this 53.5V module to operate?

The shelf must supply a compatible high-voltage DC input bus, a 3-position blind-mate connector matching the GPR4850D pin-out, and forced-air cooling slots aligned with the module's front-to-rear airflow.
