Product Overview
Computer Products PM519 is an encapsulated AC-DC linear power module delivering dual ±15 VDC output for PCB-mounted applications. It belongs to the PM500 series of encapsulated linear power modules — a product line originally marketed by Computer Products Inc. (later Power Products, later Artesyn). The brick-style enclosure mounts directly through a PCB via pin connections. Linear topology makes this module well suited to noise-sensitive analog circuits where switching ripple is unacceptable.
Key Features
- Output voltage: Dual ±15 VDC
- Output current: 100 mA per channel — Not confirmed, verify against datasheet before use
- Input voltage: 115 VAC — Not confirmed, verify against datasheet before use; some PM500 variants are fixed 115V, others support 230V
- Topology: Linear (low electrical noise)
- Form factor: Encapsulated brick, PCB pin-mount
- Case dimensions: Approximately 3.5" x 2.5" x 1.25" — Not confirmed, verify against datasheet before use
- PM500 series; dual-output variant
Applications
- Powering operational amplifiers (op-amps) and analog signal chains requiring split ±15V rails
- Legacy 1980s-1990s industrial controllers and lab instruments needing original power module replacement
- Analog-to-digital converter (ADC) supply rails in precision measurement equipment
- Repair and restoration of vintage medical or test equipment originally designed around the PM500 series
Frequently Asked Questions
What input voltage does this module accept?
The research notes indicate 115 VAC is typical for this series. However, input voltage is not confirmed for this specific unit. Some PM500 variants are fixed 115V; others support 230V or have dual taps. Verify the input configuration against the original Computer Products datasheet before connecting to mains power.
Is the dual ±15V output confirmed?
Yes. The ±15 VDC dual output is a confirmed specification for the PM519 model number.
What PCB footprint is required?
The PM519 uses through-hole pin connections and requires a PCB footprint matching the PM500 series pinout. Verify pin spacing against the Computer Products datasheet before ordering if you are designing a new board or replacing a failed unit.
Should I worry about the internal electrolytic capacitors given the age of this module?
This is a valid concern with any NOS linear supply module. This unit is unused and was stored at a distributor — it has not been powered. NOS status reduces (but does not eliminate) capacitor degradation risk compared to a used, previously powered unit. Bench-test at reduced load before installing in a live system if your application is sensitive to startup ripple.
What is included with the purchase?
The module only. No documentation, mating connector, or mounting hardware is included.
The PM519 is a discontinued series. NOS availability is limited. Confirm your PCB pinout and input voltage requirements against the original Computer Products datasheet before purchase.
