V output (V0, V2, V3):
Connector pin V is internally connected to the open collector of
an NPN transistor. The emitter is connected to Vo1- or Vo-.
VV ≤ 0.6 V (logic low) corresponds to a monitored voltage level
(Vi and/or Vo1) <Vt. The current IV through the open collector
should not exceed 50 mA. The NPN output is not protected
against external overvoltages. VV should not exceed 60 V.

Threshold tolerances and hysteresis:
If Vi is monitored, the internal input voltage is measured after the
input filter. Consequently, this voltage differs from the voltage at
the connector pins by the voltage drop DVti across the input
filter. The threshold level of option V0 is adjusted during
manufacture at Io nom and TA = 25 °C. The value of ΔVti
depends upon the input voltage range (AS, BS, etc.), threshold
level Vt, temperature and input current. The input current is a
function of input voltage and output power.
