-7 Extended Temperature Range
Option -7 extends the operational ambient temperature
range from –10 to 50 °C (standard) to –25 to 71 °C. The
power supplies provide full nominal output power with
convection cooling.
D Undervoltage Monitor
The input and/or output undervoltage monitoring circuit
operates independently of the built-in input undervoltage
lockout circuit. A logic "low" (JFET output) or "high" signal
(NPN output) is generated at pin 5 as soon as one of the
monitored voltages drops below the preselected threshold
JFET output (D1 to D4):
Connector pin D is internally connected via the drain-
source path of a JFET (self-conducting type) to the
negative potential of output 1. V
corresponds to a monitored voltage level ( V
< V
mA. The JFET is protected by a 0.5 W Zener diode of 8.2 V
against external overvoltages.
NPN output (D5 to D8):
Connector pin D is internally connected via the collector-
emitter path of an NPN transistor to the negative potential
of output 1. V
