In summary: The B&K Precision 8550 Series consists of two compact 2U half-rack programmable DC electronic loads — the 175 W 8550 and the 350 W 8551 — delivering CC, CV, CR, and CW operation, transient operation up to 20 kHz, and a built-in battery discharge test mode. The 8550 Series brings performance-tier features to a value price point.
The 8550 Series is used for general-purpose evaluation of DC power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays. Built-in functions include sweep test, load regulation, and protection limit test, making the series well-suited to power-supply characterization on the design bench and in incoming inspection.
Engineers select 8550 when they need real list-mode programming, slew-rate control, OVP/OCP/OPP protection, and front-panel remote sense in a small form factor — without paying for the higher performance tiers. The handler interface available on these loads also supports light production test integration.
8550 Series loads deliver ±(0.05% + 0.05% F.S.) CC-mode accuracy, 0.1 mA / 1 mA CC resolution, transient mode up to 20 kHz, adjustable voltage and current slew rate, and direct USB-flash data logging of voltage, current, and power. RS232 and handler interfaces are standard.
The 8550 Series is positioned as a cost-effective alternative to the performance tier — appropriate for educational labs, smaller R&D groups, and incoming-inspection stations where a 150 V × 30 A or 60 A capability covers the bulk of bench DUTs.
The 8550 is the 175 W member of the 8550 Series in a compact 2U half-rack chassis. The instrument operates in CC, CV, CR, and CW mode with ±±(0.05 + 0.05% FS) CC-mode accuracy, 0.1 mA low / 1 mA high CC resolution, and 1.5 V minimum operating voltage at full scale. Built-in capabilities include sweep test, load regulation test, and protection limit test — all of which are commonly used in power-supply incoming inspection. Direct data logging to USB flash is supported.
