Utilities and field technicians configuring distribution automation equipment often require a controlled low-voltage source to safely power devices during bench setup or diagnostic testing. To address this need, NOJA Power released the EcoLink Power Supply Unit (PSU), a tool developed specifically for powering EcoLink products in non-energised environments.
Purpose-built low-voltage supply for configuration tasks
The EcoLink PSU was engineered to provide a safe AC supply for technicians working on grid automation hardware, particularly in situations where energising equipment from line voltage is impractical or unsafe. With an output of under 7.1 V AC and selectable current levels, the unit supports laboratory configuration, firmware updates, functional testing, and training applications in utilities, service workshops, and engineering teams.
Its low-voltage operation reduces electrical risk during handling and supports compliance practices within distribution networks, where safety during off-line configuration is a priority.
Selectable current for flexible testing setups
The PSU offers two **AC RMS output current options—0.8 A or 4 A—**allowing technicians to match supply characteristics to the specific EcoLink workflow. The lower current mode suits configuration or firmware tasks, while the higher current setting accommodates procedures that require increased inrush tolerance.
Input voltage compatibility from 90 to 240 VAC at 50 or 60 Hz makes the unit suitable for global deployment across utilities operating mixed infrastructure. Regional IEC power cables (Australian, European, US and UK types) and alligator-clip connectors simplify bench setup without additional accessories.
Design considerations for utility environments
For asset management teams, the PSU provides:
- Safety: low-voltage AC output minimises risk during frequent connect-disconnect cycles in testing labs.
- Convenience: standard connectors reduce preparation time for configuration work.
- Compatibility: intended specifically for EcoLink devices, avoiding the uncertainties of third-party bench supplies.
These characteristics support routine activities such as firmware loading, communication parameter setup, or simulation of field conditions during installation training.
Position within the market
Low-voltage auxiliary supplies are commonly used in relay and automation testing environments. Comparable products exist in general laboratory power-supply ranges from manufacturers like Keysight or BK Precision, but these typically offer higher-voltage DC outputs and are not optimised for low-voltage AC supply to distribution automation equipment. The EcoLink PSU differentiates itself by matching the EcoLink’s exact operational profile, reducing configuration error and eliminating the need for improvised solutions.
Industry perspective
Neil O’Sullivan, Group Managing Director at NOJA Power, noted that the PSU was developed to simplify routine engineering tasks, emphasising its role in improving the efficiency and safety of operational workflows for utilities.
Summary
The EcoLink Power Supply Unit provides a controlled, low-voltage AC source tailored for configuring and testing EcoLink devices. With selectable output currents, global power-input compatibility and straightforward connection options, it gives utilities a safer and more predictable method for powering equipment during commissioning and maintenance procedures.
