The International Power IHA24-0.25 is a linear AC/DC converter designed for commercial information technology equipment. It accepts a selectable AC input of 115 VAC or 230 VAC ±10% at 47-440 Hz and delivers a regulated 24 VDC output at 0.25 A.
Electrical performance includes ±0.05% line and load regulation, a maximum output ripple of 5 mV pk-pk, and transient response under 50 µsec for a 50% load change. Stability is ±0.3% for 24 hours after a one-hour warm-up, and the typical temperature coefficient is 0.01%/°C. Efficiency is 45% typical.
The converter operates at full rated output from 0°C to 50°C, derating linearly to 40% output at 70°C. It is stored from -40°C to +85°C. The unit meets MIL-STD-810G vibration (6.15 g, 3 axis) and shock (20 g pk) standards. EMI/RFI compliance covers FCC CFR Title 47 Part 15 Sub-Part B and EN55022/CISPR22 Level B.
Housed in a chassis-mount package measuring 95.3 mm x 76.2 mm x 31.8 mm, the IHA24-0.25 is suitable for industrial, test, and measurement applications requiring a reliable low-noise linear power supply.
The IHA24-0.25 accepts a selectable AC input of 115 VAC or 230 VAC ±10% at 47-440 Hz.
The IHA24-0.25 measures 95.3 mm in length, 76.2 mm in width, and 31.8 mm in height, with a chassis-mount design.
The IHA24-0.25 operates at full rated output from 0°C to 50°C, derating linearly to 40% output at 70°C.
