AZO Digital 30÷80 VDC / 13,8 VDC PS-250-12V 250W spanningsomvormer galvanische scheiding, IP21

In industrial control cabinets and mobile machinery, stable low-voltage DC power is critical for sensitive electronics. The AZO Digital PS-250-12V steps down a wide 30–80 VDC input to a regulated 13.8 VDC output, delivering up to 250 W continuous power. Its galvanic isolation protects connected devices from ground loops and voltage spikes, while the IP21 rating guards against dripping water and solid objects larger than 12 mm.

Why choose it

This converter is built for demanding environments where reliability and safety are non-negotiable. The galvanic isolation barrier eliminates noise and prevents fault propagation, while the wide input range accommodates fluctuating DC sources such as batteries, solar arrays, or industrial buses. Passive cooling means no moving parts to fail, reducing maintenance and extending service life. The compact, screw-terminal design simplifies installation in tight enclosures.

Ideal use cases

• Powering 12 VDC equipment in 48 V or 72 V industrial DC systems
• Mobile and marine applications with 36–80 VDC battery banks
• Telecom and networking gear requiring isolated 13.8 VDC

Good to know

With its rugged construction and comprehensive protection, the PS-250-12V ensures continuous operation even under harsh conditions. Its passive cooling eliminates fan noise and failure points, making it ideal for noise-sensitive environments. The screw terminals provide secure connections for reliable power delivery.
