Product Overview
Calex model 1.5.1000 is an AC/DC linear power supply in a B2-type PCB mount case. It converts 115VAC input to a regulated 5VDC output at 1000mA (1A). Linear design delivers low output noise - critical for sensitive analog circuitry, precision measurement, and embedded systems where switching noise causes errors or instability. Compact footprint integrates directly onto a PCB via solder pins.
Key Features
- Input: 115 VAC ±10%, 50/60 Hz
- Output: 5 VDC at 1000 mA (1A)
- Low noise linear regulation - minimizes interference on sensitive signal lines
- Tightly regulated output for stable, consistent voltage under load
- Output overvoltage protection - clamp activates between 5.8V and 6.85V; remove power to reset
- B2-type PCB mount case with solder pins: 0.040" diameter x 0.25" length
- Dimensions: 3.5" x 2.5" x 1.25"
Applications
- Repair technician replacing a failed PCB-mount supply in industrial control equipment - solder in, verify output under load, confirm system stability before returning the board to service
- OEM engineer integrating a clean 5V rail into a new test and measurement instrument where switching noise would corrupt analog readings
- Electronics prototyper powering microcontrollers, sensors, or audio circuitry from a perfboard or custom PCB where a noisy supply would degrade performance
- Communications and radio equipment builds requiring a stable, low-noise DC supply isolated from AC line interference
Frequently Asked Questions
What input voltage does this power supply require?
115 VAC ±10%, 50/60 Hz. This is a 115V input variant. It is not compatible with 220V, 230V, or 240V mains without a step-down transformer.
Is this a switching or linear power supply?
Linear. Linear supplies produce significantly lower output noise than switching designs, which is why they are preferred for sensitive analog, audio, and precision measurement circuits. The trade-off is lower efficiency and more heat dissipation at higher loads - thermal management should be evaluated for your application.
How does the overvoltage protection work?
The output overvoltage clamp activates between 5.8V and 6.85V. To reset, power must be removed from the unit. This is not a self-resetting protection - factor this into any design requiring continuous uptime or automatic fault recovery.
Is anything included besides the power supply module itself?
The power supply module only. No documentation or accessories are included.
What is the PCB pin configuration?
Pins are 0.040" diameter x 0.25" length on a B2-type case footprint. Verify pin spacing against your PCB layout before ordering.
A linear supply this quiet has earned its keep in government lab hardware - and now it is ready for whatever precision problem lands on your bench next.
