Data centres, server farms, network operations centres and storage infrastructure cannot tolerate an interruption or a dirty output. The requirement is reliability, availability and scalability — engineered together, not bolted on.
COMPACT's YD Series is built specifically for this: a transformerless three-phase online UPS with a 0 ms transfer, 0.99 input power factor, an ultra-wide input window and paralleling for both expansion and redundancy.
Typical power issues
- Zero tolerance for transfer time on the critical bus
- High and rising load density in a fixed footprint
- Need to scale capacity and redundancy without re-architecting
- Upstream genset and switchgear sizing driven by UPS input harmonics
Recommended approach
- 01Size the online UPS to the current critical load plus 6–12 months of growth; prefer paralleled modules over one oversized unit.
- 02Use the YD Series' 0.99 input power factor and THDi < 3% to avoid oversizing generators, cables and switchgear.
- 03Build N+1 (or N+X) redundancy with paralleled units; hold battery autonomy for orderly shutdown, with a generator for long outages.
- 04Monitor over SNMP / MODBUS; wire EPO; put the fleet under a comprehensive AMC.
