Wieland expands Wipos P-series 1- and 3-? DIN-rail supplies with UPS and redundancy modules

Wieland Electric now offers DIN-rail mount UPS (uninterruptible power supply) and redundancy modules to increase control systems' uptime and reliability. These modules complement the company's existing P Series single- and three-phase power supplies. The P-series SMPSs (switch-mode power supplies) are designed for industrial applications in control panels. The single-phase models are available in 12, 24, and 48 V DC outputs, with current ranges from 1.25 to 20 A, and have a wide voltage input range—from 85 to 264 V AC and 90 to 375 V DC, depending on model. The P Power Supply Series has an operating temperature of -40 to +70 °C, and provides full output power at +60 °C. Standard features include PFC (power-factor correction), hold-up time > 30 ms, adjustable output voltage, isolated status-indicating contacts, and LED status. All P Series modules are cULus and CE-listed. Certain models are UL 1310 Class 2 and Class 1 Division 2, hazardous location-rated. The R20 redundancy module connects two power supplies in parallel and is rated at 20 A, with two inputs for power supplies and up to 20 A for one output to the load. LED and changeover (NO/NC) isolated contacts actively monitor the inputs for failure/OK status facilitating quick troubleshooting. The UPS module is rated for 24 V DC input and 30 Amp output, and when combined with commercially available lead acid batteries, will deliver continuous power. The length of backup time is dependent upon the size of the battery. The P Power Supply Series also features a built-in battery test function; under-voltage, over-voltage, and polarity protection for the battery; LED status indicators; and change over (NO/NC) isolated contacts for battery, discharge, and failure status. Pricing for the Wipos redundancy module starts at $68.89 and the UPS module starts at $155.90, both with lead times of stock to 2 weeks.
