Medium Voltage 48V Input Isolated DC-DC Power Modules

48V Input Isolated DC-DC Power Module - ATMV48VN100V80MA1, -100V output

DESCRIPTION

Analog Technologies' medium voltage 48V input isolated DC-DC power modules (ATMV48V series) convert a 36V−72V (2:1) input into a regulated high-voltage output with complete galvanic isolation. The 48V input is stepped up to a regulated high-voltage rail for the same scientific and high-voltage instrumentation as the 12V and 24V series, while drawing roughly half the supply-line current of a 24V design at equal output power. The launch model, the ATMV48VN100V80MA1, provides a regulated −100V negative single output at up to 80mA (8W). Key features:

  • 1500VDC galvanic isolation for safe high-voltage system integration
  • 2:1 input voltage range (36V−72V) for flexible 48V bus compatibility
  • Built-in automatic-recovery short-circuit protection
  • ±1% output ripple @ 20MHz for clean, stable high-voltage rails
  • Compact full-aluminum shielded DIP package (50.8×25.4×10.5 mm)
  • Wide −40°C to +85°C operating temperature range
  • Ideal for ion pumps, PMT / APD bias, piezo drivers, electrophoresis, and scientific HV instrumentation

This series is new and currently lists one model. Additional single (positive / negative) and bipolar (±) output voltages, currents, and power levels are available on request. Use the filter and search tools below to find the right part number.

Frequently Asked Questions – 48V Isolated DC-DC Power Modules

Q: What is the input voltage range of these 48V modules?
The ATMV48V series accepts 36V to 72V DC (2:1 ratio). This wide range accommodates nominal 48V bus systems with typical line and load variation.
Q: What output does the ATMV48VN100V80MA1 provide?
It delivers a regulated −100V negative single output at up to 80mA, for a rated power of 8W. The “N” in the part number denotes the negative output polarity.
Q: Does this module include short-circuit protection?
Yes — the ATMV48V series includes built-in automatic-recovery short-circuit protection, preventing damage to the module and downstream circuitry under fault conditions.
Q: What are the physical dimensions?
The 8W ATMV48VN100V80MA1 is housed in a full-aluminum shielded DIP package measuring 50.8×25.4×10.5 mm.
Q: Can ATI supply other 48V output voltages or polarities?
Yes. This series is new and currently lists one model. Additional single (positive / negative) and bipolar (±) output voltages, currents, and power levels are available on request — contact ATI with your requirements.
Q: What applications are these modules used in?
Common applications include sustaining ion pumps, spectral analysis, electrophoresis, capillary electrophoresis, particle accelerators, piezo devices, photomultiplier tubes (PMTs), and avalanche photodiodes (APDs) — the same scientific and high-voltage fields served by the 12V and 24V series.
