Country of Origin
This power module is professionally engineered and manufactured by Vero Electronics (now part of the Verotec group) in the United Kingdom.
Application Fields
The TRIVOLT PK 120 is a staple in modular electronic systems, specifically in:
- Test & Measurement: Powering precision instrumentation within VME or Eurocard racks.
- Telecommunications: Providing localized DC rails for signal processing cards.
- Industrial Control: Serving as the central power source for PLC-based automation frames.
- Laboratory Equipment: Supporting modular diagnostic and analytical hardware.
Product Usage Instructions
- Voltage Selection: Before applying power, verify that the internal jumper or rear switch is set correctly for your local mains supply (115V or 230V).
- Installation: Slide the module into the subrack guides until the DIN 41612 connector is fully seated. Secure the front panel using the captive screws.
- Wiring: Ensure the backplane wiring is rated for the maximum current of the specific DC rails used.
- Load Balancing: For optimal stability, ensure the minimum load requirements specified in the technical manual are met on the primary +5V rail.
- Ventilation: Maintain at least 1U of spacing or ensure adequate airflow if operating the unit near its maximum 120W power limit.
Product Technical Description
Technically, the TRIVOLT PK 120 (116-010047L) is a primary-switched mode power supply (SMPS). It utilizes high-frequency switching technology to provide high power density within a compact Eurocard footprint. The “TRIVOLT” designation refers to its ability to generate three independent, regulated DC outputs from a single AC source, which is essential for powering complex analog and digital hybrid circuits. The 116-010047L variant is specifically hardened against electromagnetic interference (EMI) to meet industrial CE standards.
Q&A (Common Questions)
Q: Can I adjust the output voltages? A: Most TRIVOLT PK modules feature small front-panel potentiometers (trim pots) that allow for a ±5% adjustment of the primary output rails.
Q: Is this module compatible with VMEbus systems? A: Yes, its 3U height and DIN 41612 connector make it physically and electrically compatible with many standard VMEbus and Eurocard subracks.
Q: What should I do if the “Output OK” LED is off? A: Check for a short circuit on the backplane or an overload condition. The unit features automatic recovery; once the fault is removed, the power should return.
Q: Can two modules be connected in parallel for redundancy? A: Only if the specific revision supports “current sharing.” Refer to the 116-010047L wiring schematic before attempting parallel configuration.
