General Specifications:
The document provides specifications for a DC to DC series designed for industrial PCs, telecommunication applications, and motorcar purposes. The models range from 150W to 250W. The mechanical specifications include dimensions of 150 x 140 x 86.2 mm with a tolerance of ±0.8 mm. The packing details vary by model, with net weights ranging from 1330 g to 1750 g per unit and carton sizes specified for each model.

Electrical Specifications:
The DC input uses terminal blocks, while the DC output connectors vary by application, including ATX, AT, disk driver, and floppy driver connectors. The cooling method is forced air convection, and the storage temperature ranges from -40°C to +75°C. The operating temperature varies by model, with derating applicable for temperatures above 40°C. The efficiency is higher than 65% at rated load, and the models include short circuit and over voltage protection.

Output Specifications:
Each output can temporarily provide up to the maximum load, but continuous operation above the rated load is not allowed. The document details the voltage, ripple, line regulation, load regulation, and efficiency for each model. Ripple and noise are measured using a 15MHz bandwidth limited oscilloscope.

Performance Characteristics:
The document includes performance characteristics such as output turn-on and turn-off waveforms, power good and power fail signals, and step response for voltage changes. These characteristics are illustrated with specific voltage and time divisions.

Compliance and Safety:
The models meet various safety standards, including UL 60950, CSA C22.2 No. 950, and EN60950-1. EMI radiation complies with FCC class "B" and EN55022 class "B", while EMS complies with EN61000-4-2, -3, -4, -5.
