Switching DC Power Supply features USB charging port.
Press Release Summary:
Delivering 1-36 V and 0-3 A isolated output, 108 W Model 1550 operates as constant voltage source or as constant current source. Automatic crossover to either mode of operation occurs when load condition changes. Measuring 2.8 x 6.0 x 9.8 in., microcontroller-based power supply includes over-voltage and over-temperature protection, as well as front panel-mounted USB 1.1 charging port that enables user to charge cell phone or MP3 player.
Original Press Release:
B&K Precision Introduces New Compact Switching DC Power Supply
Economical, Compact Switching DC Power Supply with USB Charging Port Provides 1-36 V, 0-3 A Output
Yorba Linda, CA August, 2008.
B+K Precision Corporation's model 1550 Switching DC Power Supply is a compact 108 Watt DC power supply delivering 1-36 V and 0-3 A to its main isolated output. Operating as a constant voltage source or as a constant current source, automatic crossover to either mode of operation occurs when the load condition changes. The unique front panel mounted USB 1.1 charging port permits the user to conveniently charge a cell phone or MP3 player.
Priced at a low $139.00 and measuring a compact 2.8" (w) x 6.0" (H) x 9.8" (D), the 1550's clean power and quiet operation makes it an ideal power supply for use in offices, laboratories, work shops, and schools where bench space is limited.
Features include:
o USB charging port on front panel*
o Rear panel security loop
o Compact design
o Output ON/OFF control
o Large, bright, easy-to-read display
o Constant voltage and constant current operation
o Over-voltage protection
o Over-temperature protection
* USB 1.1 charging port will not charge products compliant with USB 2.0 only
The model 1550 Switching DC Power Supply with USB charger port is a micro-controller-based DC power supply with USB charger output, constant current operation, over-voltage protection, floating (isolated-from-ground) output terminals, and an output on/off push button. By using the digital plus/minus (+/-) key control on the front panel, the user can easily set the output voltage and current.
The USB output is rated at 5 VDC and 0.4 A in accordance with the USB 1.1 standard. The user can power up or charge portables such as iPods, MP3 players, or cell phones, rather than having to charge the device by connecting it to a computer's USB port.
The power supply is designed to operate as a constant voltage source as long as othe load current is less than the preset current-limiting value. When the load current is equal to or greater than the preset current-limiting value, the power supply will automatically cross over to the constant current mode and the voltage will drop. When the current drops below the preset current-limiting value, the supply returns to constant voltage mode.
Priced at $139.00, the model 1550 is available for immediate delivery and comes complete with line cord, user manual, and B+K Precision's one year warranty.
