Model and Selection

Complete model PPT-125D.
Series and format PPT-125 triple-output, 5-inch × 3-inch open-frame power supply.

Cooling and Environment

Working ambient −20 to +70°C, subject to the applicable horizontal-installation derating curve.

18 CFM temperature curve The graph shows a 125% load reference through 50°C, decreasing to 50% at 70°C. Apply this plotted reference together with the separate model-specific 18 CFM current and combined-power ratings.
Input-voltage curve The 60 Hz graph rises from 80% at 85 VAC to 100% at 100 VAC and stays at 100% through 264 VAC. Operate within the specified 90–264 VAC range; the 85 VAC graph point does not extend the input rating.

EMC tests use a 360 × 360 mm metal plate, 1 mm thick. Reconfirm compliance in the completed equipment with its actual wiring and mounting; component approvals do not certify the complete system.

Weight and Reliability

Single-unit catalogue reference weight 370 g from the explicit per-unit PACKING value; a catalogue reference rather than measured net or shipping weight.
Packing reference 0.37 kg per unit; 36 pieces / 14.3 kg / 0.96 CUFT.
