New RHINO PRO (DIN Rail Performance Series) PSN and PSD series switching power supplies (from $89.00) are available in single-phase and 3- phase input units and feature universal AC input voltage range (1-Phase units), a built-in constant current circuit for charging applications (3-Phase units) and a power boost of 150% for up to 7 seconds. Current output is available from 3.4A to 40A at 24 VDC. The Advanced Power Boost (APB) feature protects the system and ensures continuing operation when a large inrush current is detected due to faulty load on a multiple load connection. A built-in DC OK contact and DC OK/Overload LED indicator are common on both series. The RHINO PSD series, with built-in LCD display, gives users the ability to verify output current, output voltage, peak hold current, lifetime expectancy and ambient temperature data.
