V ACFAIL Signal (VME)
Available for units with
Uo1 = 5.1 V.
This option denes an undervoltage monitoring circuit for
the input or input and main output voltage equivalent to op-
tion D and generates the ACFAIL signal (V signal) which
conforms to the VME standard.
The low state level of the ACFAIL signal is specied at a
sink current of
IV ≤ 48 mA to UV ≤ 0.6 V (open-collector out-
put of a NPN transistor). The pull-up resistor feeding the
open-collector output should be placed on the VME back
plane.
After the ACFAIL signal has gone low, the VME standard
requires a hold-up time
th of at least 4 ms before the 5.1 V
output drops to 4.875 V when the output is fully loaded. This
hold-up time
th is provided by the internal input capaci-
tance. See also g.:
Hold-up Time versus Output Power.

1 Option D monitors the boost regulator output voltage. The trig-
ger level is adjusted in the factory to 355 V DC.
2 Fixed value between 95% and 98.5% of Uo1.
V output (V2, V3):
Connector pin V is internally connected to the open collec-
tor of a NPN transistor. The emitter is connected to the
negative potential of output 1.
UV ≤ 0.6 V (logic low) corre-
sponds to a monitored voltage level (
Ui and/or Uo1) <Ut.
The current
IV through the open collector should not ex-
ceed 50 mA. The NPN output is not protected against exter-
nal overvoltages.
UV should not exceed 60 V.

Output conguration of options V2 and V3
Option V operates independently of the built-in input under-
voltage lock-out circuit. A logic "low" signal is generated at
pin 20 as soon as one of the monitored voltages drops be-
low the preselected threshold level
Ut. The return for this
signal is Vo1–. The V output recovers when the monitored
voltage(s) exceed(s)
Ut + Uh. The threshold level Uti is ad-
justed in the factory to 355 V DC. The threshold level
Uto
either is adjusted during manufacture to a determined cus-
tomer specied value.
