Preen ARLC Series

Automated RLC Load Bank for Anti-Islanding Test, 30kW to 250kW per Unit

Preen's ARLC series is a professional-grade RLC load simulator purpose-built for anti-islanding testing to IEEE 1547 and 1547.1, available in 30kW, 60kW, 120kW, and 250kW base models with independently controlled resistive, inductive, and capacitive loads. The modular design supports parallel connection for higher-capacity test setups, and when paired with Preen's PAS or ADG power supplies and automation software, the ARLC scales into a complete anti-islanding test platform up to 2000kW.

Base models from 30kW to 250kW, each with independently switched R/L/C loads
Simulates all four IEEE 1547.1 islanding conditions: frequency drift, voltage shift, combined drift, and matched-power (undetectable) islanding
Parallel connection expands capacity beyond a single unit's rating
Combines with PAS/ADG power supplies and automation software for a complete solution up to 2000kW
Ethernet/RS-485 remote control with automatic data logging and report generation

ARLC Series

Available as a Containerized / IP54 Option

Like Preen's BPS shore power series, the ARLC Series can be built into a customized outdoor container or upgraded to an IP54-rated enclosure as an optional configuration — useful for ports, construction sites, remote installations, and other high humidity, heat, dust, or corrosion-exposed environments. Standard indoor chassis remain the default; contact Finch to configure a containerized or IP54 version for your application.
