7? X 4.5? X 2.05? (177.8 X 114.2 X 52mm)
Pin 1(+ve) Pin2(-ve): ENABLE INPUT (Isolated from mains and outputs). When psu
used in Manual mode (see CON 4), apply +5V to enable lamp (or 12V via 1K5).
Pin 3(+ve): CURRENT MONITOR. Current shunt (0.005ohm ie 5mV/A) monitors lamp
current ie 100mV = 20A
Pin 4: LAMP REPLACE. Signal to indicate lamp needs replacing when
lamp voltage > 16V. Low output (<1V) when lamp needs replacing.
Open collector transistor output. Should use a 2K pull-up resistor to +12V FAN output.
Pin 5: CURRENT ADJUST. Can be used to remotely adjust output current by
connecting external resistance between pin 5 & 7(0V).
With lamp current set at 21A, with 10K pot fitted, typical results: 5.6K = 19A, 2.2K =
17A, 1.24K = 15A, 750R = 13A, 450R = 11A , 240R =9A 105R = 7A, 12R = 5A
Pin 6: LAMP ON. Signal to indicate lamp is ON (when lamp voltage < 24V).
Low = Lamp ON ( LED indicator can be used via 510R resistor to fan supply voltage
(connector CON 3. Pin 1 or CON 2 pin 8)
High = Lamp OFF (5.1K internal pull-up resistor fitted to12V FAN output, and 7V5
Zener in series with o/p.
Pin 7: 0V. Signal 0V. (referenced to ground). Return for pins 3,4,5,6,8
Pin 8: +12V FAN. Additional fan voltage supply connection in parallel to Con 3
Pin 9: 0V (Return of AUX. 5V)
Pin 10: +5V/1A (auxiliary, floating output. ON when Mains ON, irrespective of lamp)
Pin 11: 0V (Return of AUX. 12V)
Pin 12: +12V/2A (auxiliary, floating output. ON when Mains ON, irrespective of lamp)
Note:Aux outputs are isolated from each other and from the interface 0V and ground
Pin 1: +12V/1A - Can be used for psu fan. Only present when lamp is ON.
Pin 2: 0V ( 12V FAN Return, is referenced to ground)
Note: The fan supply is also available on CON 2 pins 7 & 8.
Pins 1-2: INTERLOCK. Supplied fitted with link. Lamp will shut down if pins open.
Pins 3-4: MANUAL/AUTOMATIC. Supplied with link fitted. If pins open lamp will
only operate using the Enable input. (See CON2 pin1&2). NOTE: pins 2,3 are joined.
Note: CON 4 is referenced to mains voltage therefore creepage / clearance distances to
Earth / ground and output need to be considered according to safety requirements.
CON 2: 12 way, 0.1? pitch, right-angle locking header.
CON 3: 2 way, 0.1? pitch, straight locking header.
CON 4: 4 way. 01? pitch, straight header, fitted with 2 jumper links.
Types fitted are Taicom TKB series
Mating connector housing type:
Taicom type TKB series
or Molex type KK series
Taicom TK series
or Molex KK series
