Read MoreThe PBB6A Series DIN Rail DC/DC Converter from Powerbox is a robust, industrial-grade power solutions designed for reliable voltage conversion in demanding fixed-installation applications. Based on COSEL’s proven STMGFS and STMGFW platforms, the PBB6A range delivers stable, isolated DC output power for control systems, instrumentation and distributed DC architectures commonly used across New Zealand industrial environments.
Available in carefully selected single and dual output variants, the PBB6A Series supports both 9–36 VDC and 18–76 VDC wide input ranges, making it suitable for 12 V, 24 V and 48 V nominal DC systems. This wide operating range allows engineers to standardise on a single converter family across multiple designs while maintaining consistent electrical performance under fluctuating supply conditions.
Depending on the model, the series provides 30 W or 80 W output power, supporting a range of regulated output voltages including 5 VDC, 12 VDC and 15 VDC, as well as dual-output configurations where split or centre‑tapped rails are required. High efficiency and stable regulation help ensure dependable operation for sensitive loads such as PLCs, sensors, communication modules and interface electronics.
All PBB6A variants supplied by Powerbox are housed in a compact enclosure with integrated DIN rail mounting, simplifying installation inside control panels and electrical cabinets. The design supports natural convection cooling and continuous operation in ambient temperatures up to +70 °C with appropriate derating, making it well suited to real‑world industrial conditions.
Electrical isolation between input and output enhances system safety and noise immunity, while integrated protection functions support long-term system reliability. Remote ON/OFF capability enables system-level power control and sequencing, supporting more advanced energy management and automation strategies.
With international safety approvals, proven long‑term reliability and a 5‑year manufacturer warranty, the PBB6A Series is a dependable choice for industrial automation, process control, utilities infrastructure, OEM machinery and fixed DC power systems where compact form factor, electrical robustness and operational flexibility are essential.
