Frequently Asked Questions

Which operating environments suit the JERBINDO CJPS C-1250 WP1 best?

This unit is designed for data center, hospital, commercial complex. With water-cooled operation and a prime rating of 1250 kVA, it supports continuous and backup operation in facilities that need high reliability.

When should I use the prime rating and when the standby rating on this unit?

The 1250 kVA prime rating applies when the generator is the main power source under varying loads, for example at sites without a stable grid supply. The 1375 kVA standby rating is for backup during outages, with use limited to no more than 10% of total annual operating hours.
