Features
independently regulated outputs: 3.3V 2.5V, 1.8V, 1.5V 1.2V Watts total output power Available input voltage ranges: 10-18V, 18-36V 36-75V Independent output voltage adjustment Remote On/Off Control Synchronous rectifier; load operation package; Industry standard pinout IEC950/UL60950/EN60950 certified mark available (75VIN models) Input under overvoltage shutdown Output overvoltage protection Thermal shutdown Fully Isolated (1500Vdc)
(Dual Voltage) Series from DATEL provides both digital core logic supply voltages from single industry-standard pinout, plastic package. series allows dual-output combination 3.3, 2.5, 1.8, Volts with associated output currents Amps 3.3V outputs Amps 1.2-2.5V outputs. combination these output currents permissable total Watts output power. models available with input ranges (-D12), (-D24) (-D48). Plug-in compatibility with number converters from other leading manufacturers possible because DATEL offers these Watt converters with flexibility add/remove higher-voltage trim (pin Each output independently regulated with control loop provide ±1.0% line load regulation. Fully synchronous output topology allows load operation high efficiencies. Models available with either positive negative on/off control. Both outputs internally synchronized eliminate asynchronous beat frequencies. models include input filtering, input overvoltage undervoltage shutdown circuitry, output overvoltage protection, output short-circuit current limiting protection thermal shutdown. These devices meet IEC950, UL60950 EN60950 safety standards. reports available request. "-D48" models marked (meet requirements).
