A new family of DIN-rail-mounted switch-mode power supplies delivers 24-Vdc control voltage at 1.25 to 40-A output current. Nine models, including six fully enclosed single-phase and three three-phase versions, operate at –25 to 71°C and have short-circuit protection.
The single-phase models accept a wide universal input voltage range, allowing one unit to operate in many applications. Input voltage for three units range from 115/230 Vac and 210 to 375 Vdc, for two units from 85 to 264 Vac and 90 to 375 Vdc, and for one unit from 115/230 Vac and 120 to 370 Vdc. Output current varies from 1.25 A to 20 A dc. Widths of the single-phase units vary from 1.7 to 6.9 in.
The three-phase units measure 3.5 × 10.9 in. and accept a 400 to 500 Vac and 480 to 820 Vdc input range. Output current varies from 10 A to 40 A dc.
All model feature touchproof screw terminations for input and output wire connections for safety.
