Technical datasheet HFX and HFXE_LED_26
-HFXE only; the indicator LED will turn green 5 seconds after first connection. This
indicates that the battery is connected and charging.
-Test of HFXE; The battery must be properly charged before this test.
- Disconnect mains supply
- The HFXE will switch the internal source to battery supply, and lamp will light up
in reduced mode.
- The preset emergency operation time 1,5 or 3 hours will be completed before the
HFXE will switch of the lamp.
- When mains supply is reconnected the HFXE will stop battery operation and return
to normal mode and normal light output.
4.1 Schedule of limitations:
- The temperature of the TC point must not be exceeded
- The minimum operating temperature of the
o HFX LED-driver is -42°C
o HFXE LED-driver is -52°C
- The HFX and HFXE LED have an output rating of 60-130V and 370mA. The current is
limited to 850mA and breaking capacity of 1500A and has been tested together with Barel
ARC LED 600 and 1200, certified Presafe 15 ATEX 6296U and IECEx PRE 15.0014U
- Charging current = 220mA, 80mA permanent
- With one fault condition of the charging system, the charging power is limited to 2W by an
transformer and the current is limited to 300mA
- Discharge current = 0.9A - 1.75A
- Discharge cut-off voltage = 4.0V for 4.8V battery.
- The fault current on the battery input is limited to 6.8A
- The indicator LED outputs has the following nominal ratings: 3V, 14mA and is limited to
5.4V and 18.3mA
- The LED-driver shall be mounted inside an Ex e luminaire and not directly exposed to light
- The terminal has a rating of 450V, Torque 0.9Nm and capacity on the screw side of one
conductor with dimensions 1.0 - 2.5mm2 rigid or flex
4.2 Electrical connection
Electrical connections of the LED-driver must be done with mains power supply off, and
disconnected. The mains supply must be disconnected by an external 2-pole switch (both phases must
be off). Connect “GND” to Protective Earth and chassis of the luminary or to a separate ground
connection. The aluminium chassis is internally connected to the gnd pin. DC input: Connect –to “N”
and + to “L/L1/L4”. HFXE: Connect L1 via switch to allow battery charging while light is switched
off. Indicator LED to be connected to 5-6 or 5-7 as indicated: (LED lamp connection according to
marking label) ( Do not connect HFX-HFXE LED to mains supply without LED lamp connected)
