Encapsulated power supplies provide a versatile
excitation source for transducers and bridges. The
barrier-strip case is designed to be mounted to a
bulkhead or chassis with four 4-40 screws. Screw
terminals are provided for connection, using either
crimp lugs or stripped wires. These regulated power
supplies are a modular solution to a user’s excitation
needs. The stable output allows drift-free performance
even if the input power source is noisy or unstable.
Long-term measurements can then be meaningfully
compared. Short circuit protection prevents failure
caused by excessive current drain, and the
conservative design ensures long-term reliability.
SPECIFICATIONS
Input Voltage: 105 to 125 Vac, 47 to 420 Hz, single phase
Ripple: 0.5 mVrms
Output Voltage Trim Adjustment:
Output is factory preset to ±2% (1 to 9V models) or ±1%
(10 to 75V models) of nominal output voltage. Output may
be trimmed to the nominal voltage rating with an external
trim resistor.
Polarity: Output is floating. Either positive or negative
terminal may be grounded.
Operating Temperature: -20 to 71°C (-4 to 160°F);
no derating required
Storage Temperature: -55 to 85°C (-67 to 185°F)
Temperature Coefficient: From 9 to 75V, approximate
TC is 0.015%/°C; 1 to 8V is 0.03%/°C
