PRODUCT OVERVIEW
The 300Wh V2 Intrinsically Safe Uninterruptible Power Supply (ISUPS 2) by Ampcontrol is designed for
Group I applications. The ISUPS converts 90 ~ 250VAC mains power into intrinsically safe low voltage
DC power with a built-in Battery Backup. A user accessible keypad, LCD screen, and indicator lamps
allow interrogation and configuration of the ISUPS. The ISUPS also provides several other intrinsically
safe monitoring and control connections.
3.1 Key Features
LCD Display with Keypad input
“Mains On”, “Output On” and “Output Overload” indicator LED’s
“Stop LED” and “Reset LED”
Local start/stop
Remote start/stop
Auto shutdown on low battery
Battery state and capacity indicators
Configurable alarms for:
o
Output over current
o
Output under current
o
Output under voltage
o
Battery over temperature
Three output relays with voltage free NO contacts. These can be configured for multiple alarm
functions. Contacts are rated at 30V/3A.
Relay 1 is suitable for use with a separate intrinsically safe circuit i.e. the contact is isolated from
the UPS intrinsically safe circuit.
Relays 2 and 3 are suitable for use on the same intrinsically safe circuit (i.e. not isolated from
each other) that may be separate to the IS circuits of the UPS or those utilised on Relay 1
Two external isolated digital inputs (DI2, DI3) that may be used to activate functions as listed in
Table 6. These can be powered from a common external intrinsically safe circuit or the ISUPS
output.
A non-isolated digital input (DI1) that can be configured to activate functions as listed in Table 6
Modbus RTU over RS485 communications port to monitor the device
Event and periodic logs
User configurable timer to shut-down the UPS, while operating from battery
This ISUPS must be installed in an upright position and may be mounted by its back or base using M6
screws. The enclosure is of a robust stainless steel construction with screw connection terminals inside
internal connection boxes on top of the enclosure. The ISUPS has two separate connection
compartments to isolate the incoming AC power from the various Intrinsically Safe Circuits.
CAUTION!
The AC power terminal compartment should
only be opened if the
external AC supply has been de-energised.
Opening this
compartment in a hazardous area when the AC supply is energised is
not permitted.
WARNING!
THE MAINS VOLTAGE COMPARTMENT
MUST NOT BE OPENED
WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT.
