Philtek HPRi 3 Phase Modular Inverter System
  • 48 VDC Input

  • 90 kVA to 180 kVA

  • 277/480 VAC 3 Phase

  • Expansion and Redundancy
Inverter Modules “Plug and Play”
- 10 KVA output each
- High frequency PWM technology, quiet operation
- “Hot Pluggable”, allows installation or removal of modules
without de-energizing the system
- Output compatible with Active Power Factor Corrected AC
Loads
Static Bypass Switch and Controller
- Output power rating self configured, 2 mSec transfer time
- Microprocessor Controlled with LCD display and Industrial
style LED Mimic Diagram
- User configured to operate in the On-line ( Inverter preferred )
or the Off-line (AC line preferred ) mode
- Provides an additional level of redundancy when operated in
the On-line Mode		 - Plug in modular construction, can be removed or installed with
no output interruption during Maintenance Bypass
- Optional RS-232 Communication Port available
AC Power Plant
- Constructed of heavy duty 23” racks
- Make Before Break Maintenance Bypass Switch provides
uninterrupted output during bypass
- AC line Circuit Breaker for overload protection during Static
Bypass
- Fully enclosed AC and DC power bus bars, pre-wired to
terminal blocks for external connections
- Inverter docking trays provide easy plug in and removal of
Inverter Modules
- CSA Certification pending
- UL 1778 Certification pending
