Example Power Specification

Please find below an example power specification for a typical TEAL power subsystem for the medical imaging market. This type of information is helpful to TEAL in understanding your system power requirements, and allows us to work with you in designing the optimal power subsystem solution.

One example of a typical power specification would include these inputs from the customer for an isolation transformer based product:

Model Number: PCDU-XT150 (for Purchase Order reference)

Input Voltage: 200/208/240/380/400/415/440/480/500VAC 3-Phase Delta (4-wire)

Frequency: 50/60Hz

Main Output: 480/277VAC 3-Phase Wye (5-wire), 190A/phase peak, 42A continuous (determines power requirement)

Second Output: 120VAC 1-Phase, 20A Fuse protection, 2 each 5-20R Duplex Outlets

60Hz Impedance: < 0.06 Ohms Line-Neutral (transformer impedance specification)

Load Regulation: < 1.8% at 190A/phase peak (refers to voltage "sag" during high peaks)

Input Protection: Programmable Circuit Breaker, 250A frame, adjustable for 200VAC to 500VAC input

Controls: Shunt-trip control of input CB (through terminal block) for remote Emergency Power Off control

Audible Noise: Less than 50dB (A) audible noise measured at 1 meter

Agency Approvals: UL Listed to Standard 1012/187 for Power Supplies and X-Ray

Physical Size: Less than 22" wide, less than 22" deep, less than 48" tall, and less than 1000 lbs weight

This type of information is very helpful in optimizing a power subsystem.
