1 AM...LM 1000 types equipped with option P do not provide the R input simultaneously, pins 14 and 17 are not connected.
Option -9 Extended temperature range
Option -9 extends the operational ambient temperature
range from –25...71
°C (standard) to –40...71°C.The power
supplies provide full nominal output power with convection
cooling.
Option P Potentiometer
Optionally built-in multi-turn potentiometers provide an out-
put voltage adjustment range of minimum
±5% of Uo nom
and are accessible through holes in the front cover. Com-
pensation of voltage drop across connector and wiring be-
comes easily achievable. For output voltages
Uo > Uo nom,
the minimum input voltage according to "Electrical Input
Data" increases proportionally to
Uo/Uo nom.
Note: Potentiometers are not recommended for mobile ap-
plications
Option A Test sockets
Test sockets (pin = 2 mm, distance d = 5.08 mm) are lo-
cated at the front of the module. The output voltage is
sensed at the connector pins inside the module.
