When precision matters down to parts-per-million and noise can corrupt an entire imaging sequence, power-supply design becomes mission-critical. XP Power’s new HRF15 series of high-voltage DC-DC converters is built for exactly that challenge.
What’s New & Why It Matters
The HRF15 series delivers:
-
Voltages up to 15 kV from a single +24 VDC input.
-
Output ripple as low as 0.001% and long‐term drift at 10 ppm/hr (or 25 ppm over 8 h).
- Temperature coefficient of 25 ppm/°C and line/load regulation down to 10 ppm, enabling stable operation in variable ambient conditions.
- Programmable output from 0-100% of voltage/ current, voltage & current monitoring built-in, plus short-circuit and overload protection.
- A compact metal enclosure (≈ 162 × 72.4 × 33 mm, ~465 g) suited to space-constrained analytical equipment.
For engineers working in analytical instrumentation, mass spectrometry, SEM/TEM, e-beam lithography, capillary electrophoresis, or other noise-sensitive applications, these specs translate directly into better measurement integrity, fewer artefacts, and more reliable system performance.
Engineering Implications for Design Teams
Here are the practical take-aways:
-
Noise floor wins big: In detectors or beam systems, noisy HV supplies can degrade resolution, induce drift, or trigger false signals. The HRF15’s ultra-low ripple helps avoid that.
-
Compact seat in tight systems: With high voltage and high precision in a relatively small form factor, you can place the converter closer to the point of use—reducing parasitics and improving fidelity.
-
Built-in monitoring & protection: Having current and voltage monitors, plus overload/short protection, simplifies both system integration and reliability qualification.
-
Thermal & ambient tolerance: The low temperature coefficient and tight regulation mean fewer compensations for ambient change—especially helpful in environments where cooling, temperature control, or airflow are constrained.
-
System simplification: Rather than piecing together bespoke high‐voltage supplies, this module gives a plug-in high-precision option, freeing up design effort for downstream instrumentation and mechanics.
Why This Release Matters Now
As analytical instruments advance—with higher beam currents, finer resolution, denser integration, and more demanding environments—the power supply becomes more than a supporting component: it becomes a performance enabler. XP Power stepping up with a high-voltage, ultra-low noise, compact DC-DC converter closes a gap for system architects pushing the envelope.
For engineers designing next-gen instrumentation, this means fewer custom builds, lower integration risk, and a stronger chance of hitting performance targets on schedule.
