INV2500-HS SERIES INVERTERS & SHELVES
OPERATING MANUAL
1.0 INTRODUCTION
1.1
This Operating Manual should be read through carefully before installing and operating
the INV2500-HS inverter modules and shelves. See Figure 1.
1.2
The INV2500-HS is a 2500 volt-ampere, hot-swap, DC to AC inverter module. It con-
verts a nominal 48VDC input into a 115 or 230VAC output at 50 or 60Hz. These mod-
ules are designed to go into a 19-inch, hot-swap compatible shelf, INVR2U-HS, which
holds one or two units. When two modules are used in this shelf they are automatically
connected in parallel and synchronized to produce 5000 volt-amperes at 115VAC output
(44 amperes) or 230VAC output (22 amperes). Or they can be operated in a 1+1 redun-
dant mode at 2500 volt-amperes.
1.3
The 48VDC nominal input has a range of 42 to 56VDC. The inverters achieve 90% ef-
ficiency and 7VA per cubic inch power density. Input and output are both circuit breaker
protected. They have high surge capability for starting loads such a motors, but the
output breaker quickly trips if power attempts to flow back into a faulted inverter.
1.4
These inverters can be paralleled for higher output power or for N+1 redundant applica-
tions. They are fully isolated from the battery. Front panel LEDs indicate inverter status,
and Form C relay alarm contacts are available on the back. The units are self-cooled by
internal fans.
1.5
In this manual, unless otherwise stated, INV2500-HS shall generally refer to both
INV2500-HS and INV2500H-HS (115 and 230VAC) inverter models. Likewise INVR2U-
HS shall generally refer to both INVR2U-HS and INVR2U-HS-H shelf models.
