With an MTBF (mean time between failures) rating of more than 114 years, the new INSTA POWER high-efficiency single-phase power supplies from Weidmüller are true fit-and-forget components. They are available with ratings up to 96 W and feature a compact design that is ideally suited for use in the small cabinets that typically make up today’s decentralised control systems, as well as small distribution boards, meter cabinets and electrical distribution panels often used in building automation and machinery industries. These innovative power supplies use Weidmüller’s unique PUSH-IN connector technology, which significantly reduces wiring time and guarantees reliable connections.
INSTA POWER switch-mode power supplies also save energy, thanks to their exceptional 91% efficiency and their minimal no-load power requirements of just 0.5 W. The immediate and important benefits are reduced heat generation, which is particularly pertinent in small enclosures, lower running costs, and a smaller carbon footprint.
Weidmüller’s new power supplies are convenient to install, as they can be instantly clipped onto a standard mounting rail or alternatively mounted directly on a baseplate. They also have a wide operating temperature range of -25 ºC to +70 ºC, which makes them suitable for use in a wide range of applications and environments. Their versatility is complemented by a full array of international approvals which means they can be fitted in equipment destined for use anywhere in the world.
Weidmüller currently offers its new INSTA POWER power supplies in nine versions, with nominal output voltages of 5 V, 12 V, 24 V and 48 V DC. In each case, the output voltage is adjustable over a small range via a screwdriver-operated potentiometer on the power supply front panel, which is useful, for example, to compensate for voltage drop in connecting leads. The smallest power supplies are rated at 16 W and the largest at 96 W. The input voltage range for all types is 85 V to 264 V AC, 45 Hz to 65 Hz, or 95 V to 375 V DC.
