IIS INVERTERS
The IOTA IIS-375-LED is a UL Listed stand-alone sine wave output inverter designed to provide power to designated emergency lighting fixtures. In a power
loss situation, the IOTA IIS-375-LED will supply 375W of power from the onboard battery supply. The IOTA IIS-375-LED is specifically designed for LED
applications and will prevent shutdown caused by inrush currents of LED drivers. The IIS-375-LED is ideal for applications requiring an emergency source
for lighting arrangements utilizing multiple LED fixture types, and will automatically run switched, normally-on, or normally-off designated emergency fixtures. The
IIS-375-LED is available in a surface mount housing and comes with a three-year
warranty and seven-year pro-rata battery warranty.

375W SURFACE MOUNT UNIT INVERTER SYSTEM
IIS-375-LED SAMPLE SPECIFICATION
Emergency lighting shall be provided by inverter unit equipment designed to
operate designated LED fixtures on emergency power at their full nominal lumen
rating during the full 90 minute emergency discharge cycle. System output will be
rated at 375 watts for 90 minutes and provided with an output circuit breaker for
protection of overload or load fault conditions. The system’s voltage rating shall
be field selectable 120 or 277 VAC input/output.
ORDERING GUIDE
IIS-375-LEDDR
Dimming Relay
(Optional) See below for
application details.
(blank)
The inverter unit shall allow for connected emergency fixture(s) to be normally
on, normally off, switched or dimmed without affecting lamp operation during a
power failure. Upon utility power loss, the inverter unit shall operate the load at
100% of its full rated output regardless of the local switch position, and will provide
power to emergency fixtures at distances of up to 1000 feet.
No Dimming Relay.
The housing shall be designed for surface mount installation requirements and
manufactured using 16-gauge steel with a white hammer semi-gloss scratchresistant baked-on powder coat paint finish.
COMPONENTS
High-efficiency pure sine wave inverter
Variable-rate, temperature-compensated charger
The unit’s electronics shall include a self-contained inverter section with a fully
automatic, thermal-compensating variable-rate battery charger, AC lockout
feature, low battery voltage disconnect, DC overload, short circuit and brownout
protection as standard. The unit shall utilize a sealed lead calcium battery with a
10-year design life. The inverter system shall be UL 924 Listed and labeled. The
unit shall be covered under a 3-year warranty on the electronics and battery and a
7-year pro-rata warranty on the battery. It shall meet or exceed the requirements
of UL 924, NFPA 101 Life Safety Code, NFPA 70 National Electrical Code, OSHA
and State and Local codes.
12V maintenance-free Valve Regulated Lead Acid
(VRLA) battery
CONSTRUCTION
16-gauge steel housing
The inverter unit shall be IOTA model IIS-375-LED.
TYPICAL WIRING
Internal Circuit Breaker
The internal circuit breaker protects
the inverter from overload on the
output side of the unit. Internally, the
appropriate voltage lead is selected
for connection to the line side of the
circuit breaker and the designated
emergency load connects to the single Yellow/Violet 120/277V hot lead.
