FSP PU60 Series 37.5-64 Watt ITE Power Supplies

Description

The PU60 series comprises compact, open PCB constructed, AC-DC switching power supplies. These units are capable of delivering 37.5 to 64 watts of continuous output power under convection cooling. They operate with a wide-range input voltage of 90-264 VAC, eliminating the need for manual voltage selection. The series is well-suited for applications in data networking, computer systems, telecommunications, audio/video equipment, and industrial environments.

Features

Output Voltage/Current Rating Chart

Notes:

1. Safety approvals are for PCB form only. To order units with a cover fitted, change the suffix "A" to "C".
2. Maximum current for output #1 on multi-output models can be 8 A when using 5 CFM forced air provided by the user.
3. 47.5 W rating is applicable with 5 CFM forced air provided by the user.
4. Output voltages on multi-output models may deviate from stated tolerances if an output load current is outside the stated limits. All models can be operated without load and will not be damaged.
5. Ripple and noise is the maximum peak-to-peak voltage measured at the output within a 20 MHz bandwidth, at the rated line voltage and output load ranges. A 10 µF tantalum capacitor in parallel with a 0.1 µF ceramic capacitor is placed across the output.

Mechanical Specifications

The power supply unit has a compact open PCB construction. Key dimensions are approximately 2 inches (width) x 4 inches (depth) x 1.18 inches (height). Mounting holes are provided, with a diameter of 0.157 inches (4.00 mm) for four mounting points. A ground tab is also present, measuring 0.25 inches (6.35 mm) by 0.032 inches (0.8 mm). Connector CN1 is a Molex header (part number 09-65-2038 or equivalent) mating with Molex housing 09-50-1031 or equivalent. Connector CN2 is a Molex header (part number 09-65-2068 or equivalent) mating with Molex housing 09-50-1061 or equivalent. To comply with Level B emissions, two mounting holes marked with an asterisk (*) should be connected to the chassis using metallic standoffs. The approximate weight of the unit is 205 grams (0.45 lbs).

Output Power Derating Curve

The output power derating curve illustrates the relationship between ambient temperature and maximum output power. The graph shows Output Power (%) on the vertical axis and Ambient Temperature (°C) on the horizontal axis. The curve starts at 100% output power at 50°C and decreases linearly to 50% output power at 70°C. The operating temperature range shown is from -10°C to 70°C.
