TECHNICAL INFORMATION
1.1
General
1.1.1
Battery Backed Power Supply RIP-24 model 01 (RIP-24-3/7M4) (referred to as
the RIP below) is designed to provide electric power to various fire and intrusion detectors
as well as control and indicating equipment which require uninterrupted 24 VDC for
operation.
1.1.2
The RIP is round-the-clock operating device with specified output parameters and
sealed backup batteries which are tested and charged automatically. The RIP provides
shutting the batteries off from the load circuit to avoid their unacceptable discharge.
1.1.3
The RIP provides light and audible indication of its current status, i.e. of normal or
no voltage, battery charge, output short failure or overload, battery missing or shutting down
when discharged.
1.1.4
When operated, the RIP should be protected against atmospheric fallout and
mechanical damage. The RIP is not designed to be used in explosion-hazardous premises.
1.1.5
In terms of climate tolerance, the RIP meets the conditions of moderately cold
climate, installation Category III as per GOST 15150-69, but to be used within temperature
ranges of 263
К
to 313
К
(-10°
С
to +40°
С
) and ambient humidity of up to 90% at 298
К
(25°
С
).
1.1.6
In terms of mechanical tolerance, the RIP corresponds to Category LX in
accordance with GOST 12997-84: vibration within 1Hz to 35 Hz when accelerated up to 4.9
m/s
2
(0.5 g).
1.2
Specifications
1.2.1
The main power supply is the mains power
150…253 V, 50Hz.
1.2.2
The backup battery power supply is represented by two batteries «Delta» DTM1207
(12 V, 7 Ah) or similar with equivalent parameters (with five-year life time at least).
The RIP is supplied with no batteries!
1.2.3
The rated output voltage is 27.0
±
1.2 V when powered by mains and the batteries
are charged (if the batteries are discharged the minimum output voltage is 22.0
±
1.0 V).
1.2.4
The rated load current is 3 A.
1.2.5
The maximum load current (for short-duration periods once per an hour) is
4 A/2 minutes (when powered by mains and the batteries are connected).
1.2.6
The current consumed from mains at rated load and maximum battery charging
rate:
-
1.3 A max at 150 V input voltage;
-
0.9 A max at 220 V input voltage.
1.2.7
The current consumed by the RIP itself from the battery doesn’t exceed 30 mA.
1.2.8
Ripples of the output voltage (peak-to-peak) at normal load current don’t exceed
60 mV.
1.2.9
The low battery shutdown voltage is 20.4
±
1.2 V.
