SAA Field Power Unit

The SAAField Power Unit (SAAFPU) is a portable, rugged, all-in-one power and communication device designed specifically for manual data collection in field.

The SAA Field Power Unit (SAAFPU) is a portable, rugged, power and communication (interface) device designed for manual data collection in the field. Everything needed for the field is enclosed within a lightweight, water-resistant case. SAAFPU contains a rechargeable 12V 7Ah battery, 5-pin and 4-pin communication ports, a bluetooth adapter set for wireless data transmission, and a shoulder strap for additional portability. An auxiliary 4-pin terminal block can be used to power other equipment such as a radio modem or voltmeter.

The SAAFPU is designed to meet ShapeArray’s unique power requirements. ShapeArrays often contain hundreds of sensors. A high quality DC to DC converter that boosts and regulates voltage to a constant 13.5V. Output voltage can be boosted up to 16.5V for long ShapeArrays and cables. To recharge the battery, plug the unit into a standard power outlet.

The SAAFPU connects to any ShapeArray model via USB cable or wirelessly up to 100 m via pair of wireless adapters included in the box. A USB port driver is required to operate the SAAFPU and is included in the downloadable SAARecorder application via SAASuite.
