Product Overview
Calex Model 3.15.5 is an AC/DC triple-output linear regulated power supply module housed in an encapsulated PCB-mount case. Operating from standard 115 VAC line power, it provides dual tracking ±15 VDC outputs rated at 100 mA alongside a separate +5 VDC logic rail delivering up to 500 mA. The linear regulator design maintains low electrical noise and ripple, supplying clean analog and digital operating voltages directly on through-hole printed circuit boards.
Key Features
- Output rails: ±15 VDC at 100 mA and +5 VDC at 500 mA
- Nominal input voltage: 115 VAC, 50/60 Hz
- Encapsulated module construction for environmental and physical protection
- Through-hole solder pin mounting for direct circuit board integration
- Terminal pin markings on faceplate for AC, +15V, -15V, CMN, +5, and 5V CMN
- Low-noise linear regulation suitable for sensitive analog signal paths
Applications
- Replacing power modules in legacy industrial controllers, instrumentation racks, and laboratory test gear.
- Powering split-rail operational amplifiers and analog-to-digital converter circuits alongside 5V logic on prototype boards.
- Building dedicated low-noise bench supplies for audio preamplifiers, synthesizer modules, or mixed-signal development.
Frequently Asked Questions
Does this unit have separate common pins for the outputs?
Faceplate markings show dedicated pins for CMN and 5V CMN alongside +15V, -15V, +5, and AC.
What case size is this module built in?
This unit is housed in an encapsulated B2 case with solder pins on the base.
What input power source does this module require?
Operating power is 115 VAC nominal at 50/60 Hz.
Each piece costs less as the order grows - see the price-break table on this page.
Encapsulated linear supplies like this were built for clean rails and quiet grounds when switching noise was not an option. Wire it into the board, fire up your op amps, and get back to work.
