The first models introduced are the 15W PDA15F, the 30W PDA30F, and the 50W PDA50F, with more versions to follow. The PDA series is designed for use in a wide range of applications and can operate in a broad temperature range of -20 to +70 degrees Celsius. The power supplies are UL/EN62368-1 certified.
Designed for all types of applications, the PDA series has an input voltage range of 85 VAC to 264 VAC single-phase and meets safety standards with an input voltage range of 100-240 VAC (50/60 Hz).
The 15W PDA15F, 30W PDA30F, and 50W PDA50F are available in three output voltages: 5V, 12V, and 24V, with their corresponding output currents. The output voltage can be adjusted using an output voltage potentiometer.
The PDA series benefits from an optimized, near-resonant switching topology and boasts an efficiency of up to 87.5% at 230 V AC and rated load. Compared to the original PBA model, this represents an efficiency increase of over 5 percentage points, reducing heat dissipation and consequently increasing system reliability.
The PDA series includes inrush current limiting, overcurrent protection with automatic recovery upon clearing of the fault, and overvoltage protection.
Based on an optimized topology, the PDA series does not incorporate active PFC, although it fully complies with IEC 61000-3-2 (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 power reduction 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 standards for conducted emissions testing.
The units have an input-to-output isolation voltage of 3,000 VAC, an input-to-frame-to-ground (FG) voltage of 2,000 VAC, and an output-to-frame-to-ground voltage of 500 VAC.
The PDA series is housed in a galvanized steel chassis and offers an optional "N" cover.
Designed for demanding applications where space is often limited, the PDA15F measures only 31 x 78 x 85 mm (1.22 x 3.07 x 3.35 in) and weighs a maximum of 180 g without the cover and 210 g with the cover. The PDA30F measures 31 x 78 x 103 mm (1.22 x 3.07 x 4.06 inches) and weighs a maximum of 250 g without the cap and 280 g with the cap. The PDA50F measures 31 x 82 x 120 mm (1.22 x 3.23 x 4.72 inches) and weighs a maximum of 330 g without the cap and 370 g with the cap.
The PDA series is compatible in form, fit, and function with the PBA series and they are mechanically interchangeable.
The PDA15F, PDA30F, and PDA50F models are suitable for a wide range of applications, including process measurement and control, machine monitoring, display devices, and a variety of industrial equipment. They comply with RoHS and low-voltage standards and bear the CE and UKCA marks.
