New Compact Single Phase AC DIN-Rail Switch Mode Power Supplies
Shawn Martin | March 02, 2018Carlo Gavazzi introduced two new single-phase AC DIN-rail switch mode power supply families in housings that are among the most compact available. The new Slimline Power Supplies include features and price points that are well-suited for a wide variety of markets and applications.
The SPDM Series is their general purpose family with industry standard features in the most common output configurations. They are available in ranges from 30 watts (W) up to 240 W, in 12-volt (V) and 24-V outputs, and their housings are up to 30 percent smaller than similar types on the market.
The SPDC Series offers the highest level of features and performance and are also available in slim metal housings. They feature efficiency levels above 90 percent, built-in power factor correction, and can provide 150 percent power boost for up to three seconds, which is ideal for applications with high inrush currents. A built-in parallel function and an output ready relay help ensure power is always available for critical functions. These advanced models are available in 120-W, 240-W and 480-W-output versions.
Technical features of the SPDM Series include:
- Universal input voltage 85-264 volts of alternating current (VAC) and 120-375 volts of direct current (VDC)
- Output voltage: 12 V and 24 VDC
- High efficiency up to 89 percent
- Overvoltage, short circuit, and overload protection
- Compact dimensions
- Spring or screw terminals
- UL1310 Class 2 (models under 100 W)
Technical features of the SPDC Series include:
- Universal input voltage 85-264 VAC and 120-375 VDC
- Output voltage: 12 V and 24 VDC
- High efficiency up to 94 percent
- Overvoltage, short circuit, and overload protection
- Parallel connection
- Power boost up to 150 percent for three seconds
- Built-in DC OK (power good signal) relay contact
The SPDM Series and SPDC Series power supplies are UL and cUL listed, and TUV and CE approved. They are available from Carlo Gavazzi’s network of sales offices, distributors or at www.GavazziOnline.com.
Moving forward, the SPDM Series and SPDC Series are ideally positioned to be the primary DIN Rail power supplies from Carlo Gavazzi. They contain the most important features that the market requires today. They will continue to offer prior generation SPD Series but will begin transitioning their inventory levels to reflect the emphasis of SPDM Series and SPDC Series.
