COSEL has announced the launch of the PDA series of AC/DC power supplies with further enhanced reliability for industrial applications. The first units are now being launched and the range will be expanded.
Designed for worldwide applications, the PDA series has an input voltage range of 85VAC to 264VAC single phase and meets safety standards with an input voltage range of 100-240VAC (50/60Hz). The 15W PDA15F, 30W PDA30F and 50W PDA50F are available in three output voltages, 5V, 12V and 24V with corresponding output currents. The output voltage can be adjusted by a built-in potentiometer. The series benefits from an optimised quasi-resonant switching topology and has an efficiency of up to 87.5% at 230VAC and rated load. Compared to the previous PBA series, the efficiency increase is more than 5 percentage points, reducing heat dissipation and increasing system reliability.
Mountable in any orientation
Inrush current limiting, over-current protection with automatic recovery when the fault is removed and over-voltage protection are part of the PDA functionality. Based on an optimised topology, the series has no built-in active PFC but fully complies with IEC61000-3-2 (Class A). The units are designed to operate over a wide temperature range of -20 to +70 °C and can be mounted in any orientation, although derating may apply depending on ambient temperature and environment. The PDA series complies with FCC-B, VCCI-B, CISPR11-B, CISPR32-B, EN55011-B and EN55032-B in conducted emission tests. The units have an input-to-output isolation voltage of 3,000 VAC, an input-to-frame-ground (FG) voltage of 2,000 VAC, and an output-to-frame-ground voltage of 500 VAC.
Compact design
Designed for use in demanding applications where space is often limited, the PDA15F measures just 31 x 78 x 85mm and weighs 180g max without cover, and 210g with cover. The PDA30F measures 31 x 78 x 103mm and weighs 250g max without cover, and 280g with cover. The PDA50F measures 31 x 82 x120mm and weighs 330g max without cover, and 370g with cover. The PDA series is form, fit and function backwards compatible with the PBA series and are mechanically interchangeable. They are RoHS and Low Voltage compliant and carry the CE and UKCA marks.
