Product catalog summary
Overview: The document provides detailed specifications for the POWERBOX Industrial Line 300, OBP37 Series, a 300W single output AC/DC switch mode power supply. It includes information on features, input and output specifications, environmental conditions, general characteristics, interface signals, standards compliance, and mechanical details.
Features: The power supply operates at altitudes up to 5000 meters and has a compact footprint of 3 x 6 inches with a low profile of 1.5 inches. It accepts a wide input voltage range of 100-240 VAC with active power factor correction (PFC) and achieves a high efficiency of 92% typical. It includes protections such as short-circuit protection and a Power Fail Detect (PFD) signal. The device is RoHS compliant and consumes less than 1W in standby mode.
Input Specifications: The input voltage range is 90-264VAC with a frequency of 47-63Hz. The current is 4.0A for 115VAC and 2.0A for 230VAC, with a maximum leakage current of 220mA at 264VAC, 63Hz.
Output Specifications: The output power and voltage/current specifications are detailed in a table. Ripple and noise are limited to 1% peak-to-peak maximum. The power supply includes remote sensing for cable loss compensation, over-voltage protection, and over-current protection. It also features a transient response with a maximum excursion of 4% or better.
Environmental Conditions: The operating temperature range is 0°C to +70°C, with storage temperatures from –40°C to +85°C. Relative humidity is 5-95% non-condensing. Derating is required from 100% at +50°C to 50% at +70°C.
General Characteristics: The switching frequency is 100KHz typical, with a minimum efficiency of 87% across all models. The power supply has a turn-on delay time of 3ms max at 100VAC and a hold-up time of 10ms min at 110VAC. It withstands voltages of 3,000VAC from input to output.
Interface Signals: The PFD signal indicates normal operation with TTL logic high and signals loss of input power with TTL logic low. The inhibit function requires an external TTL high level signal to disable outputs.
Standards Compliance: The power supply meets safety standards such as UL60950-1 and EMC performance standards including EN55011/EN55022 Class B. It also complies with various EN61000 standards for electromagnetic compatibility.
Mechanical Details: The document provides mechanical specifications for different forms (PCB, L-bracket, enclosed) with details on connectors and pin configurations. The weight varies depending on the form, with the PCB form weighing approximately 510 grams.
