The B&K Precision XLN Series is a family of programmable single-output DC power supplies that deliver up to 1560 watts of clean DC power in a compact 1U rackmountable package. The series spans seven models ranging from 0–36 V at 40 A through 5–600 V at 2.6 A, addressing both benchtop users and system integrators in a single product line.

The XLN Series is positioned for ATE systems integration, product design and development, product QC and burn-in testing, and other applications requiring excellent regulation, high power, low noise, and a wide range of voltage and current ratings. Front-panel operation uses a full keypad and rotary knob with concurrent display of setting and output values for bench work, while the standard USB and RS485 interfaces and the optional GPIB and LAN on -GL versions support automated test environments.

## Compare Other Models in This Series

The XLN Series divides cleanly into two architectural groups that share the 1U chassis, the SCPI command set, and the interface complement, but differ in their output envelope and a few feature details. High-current models — XLN3640, XLN6024, XLN8018, and XLN10014 — cover 36 V to 100 V at currents up to 40 A within a 1440 W output envelope. High-voltage models — XLN15010, XLN30052, and XLN60026 — extend the family to 150 V, 300 V, and 600 V outputs at correspondingly lower currents within a 1560 W envelope.

Beyond the output ratings, the two groups differ on three feature dimensions documented in the family specification table: high-current models include a fixed 5 V / 1 A auxiliary output and support both parallel and series master/slave operation, while high-voltage models omit the auxiliary output and support parallel master/slave only. High-current models also offer 1 mV / 1 mA display resolution, while high-voltage models use 10 mV / 1 mA resolution scaled to their wider voltage ranges. Both groups offer analog programming; analog monitoring is listed as a high-voltage-model feature.

Each new XLN model below is listed on its own product page with model-specific pricing and condition documentation. Use the comparison table to identify the output envelope and feature set that fits the application, then visit the individual product page for the exact model to see availability and request a formal quote.

Within the high-current group, the four models differ primarily in the voltage/current trade-off at a constant 1440 W power envelope. XLN3640 delivers the highest current (40 A) at the lowest voltage (36 V) and is suited to low-voltage, high-current loads. XLN6024 (60 V / 24 A), XLN8018 (80 V / 18 A), and XLN10014 (100 V / 14.4 A) walk progressively higher in voltage as current scales down. All four share the 5 V / 1 A auxiliary output, parallel/series master-slave capability, and 1 mV / 1 mA display resolution.

Within the high-voltage group, the three models step from 150 V (XLN15010 at 10.4 A max), to 300 V (XLN30052 at 5.2 A max), to 600 V (XLN60026 at 2.6 A max), all within a 1560 W envelope. Their minimum output currents start at 0.04 A, 0.02 A, and 0.01 A respectively, reflecting the higher-voltage application targets. The comparison table below summarizes the output ratings and feature differences across all seven family members; consult it before selecting a specific model for an application.
