GPAC Portable Power Solutions

 

The GPAC Portable Power Solution is an organized system of batteries, cases, chargers, cables, and power accessories, to supply 12 volt power to various types of GPS and Survey Instruments.

The Portable Power Solution is designed to deliver optimum power in a safe, easy to carry package. The system eliminates the caustic, fume producing lead acid batteries that are difficult to handle safely, can tip over and spill acid, and can produce corrosive fumes that are detrimental to your expensive GPS and Survey equipment.

The Portable Power Solution batteries are totally enclosed to prevent accidental contact with the battery posts causing short circuits that can ruin the battery. The batteries are recharged through either of the outputs so you never need to access the battery directly. They are spill proof, can be operated upside down, and don't produce any corrosive fumes.

The system employs a heavy duty, 1000 denier, highly visible, Fluorescent Orange or Neon Green, DuPont Cordura carrying case. The cases are non-conductive, very strong, and have a built-in storage compartment for the battery cables, output connectors, and accessories. Carry straps have a soft molded handle that is comfortable and balances the weight evenly in your hand.

All models have two power outputs terminated using Anderson Power Pole connectors and or a covered SAE 2-pin connector. Anderson Power Pole connectors are genderless allowing them to mate with themselves. Cables and accessories exchange between the different models and multiple packs can be plugged together to increase the total capacity of any one pack.

There are many different battery cables and accessories available to power virtually all models of Survey Equipment including Ashtech, Leica, Pacific Crest, Sokkia, Topcon and Trimble models. Custom cables are available on special order that combine data collection and power into a single cable. Useful for instruments that only have a single shared connector for both power and data.

Available in 5 sizes:

  • Model 1209 - 12 Volt, 9 Amp Hour
  • Model 1218 - 12 Volt 10 Amp Hour
  • Model 1218 - 12 Volt, 18 Amp Hour
  • Model 1235 - 12 Volt, 35 Amp Hour
  • Model 1250 - 12 Volt 50 Amp Hour

 

Model 1209 12 Volt 9 Amp Hour Pack

The Model 1209, 12 volt 9 amp hour pack features 2 - 15 amp fused outputs with Anderson Power Pole connectors.

The 1209 weighs approximately 6 pounds.

The pack can deliver 12 watts of power for 9 hours. (108 watt/hours)

For illustration, according to Trimble's published specifications, a model R8 GNSS receiver's power consumption is 3.2 Watts. Therefore a fully charged 1209 pack will operate that R8 for approximately 33 hours. The math: 108 watt/hours divided by 3.2 watts equals 33.8 hours.

Here are some other GPS models and their power consumption and operation time using the 1209 pack:

  • Topcon HiPer Lite - 4.2 watts (25 hours)
  • Sokkia GSR2700IS - <5 watts (21.6 hours)

One of the two outputs can be used for recharging the pack. The charger cable mates with either of the two outputs. This insures that the charger is correctly connected to the battery. The supplied charger (included in the complete package) will recharge the battery in 9 hours or less.

Model 1210 12 Volt 10 Amp Hour Pack

The Model 1210, 12 volt 10 amp hour pack features 2 - 15 amp fused outputs with Anderson Power Pole connectors.

The 1210 weighs approximately 2 pounds.

The pack can deliver 12 watts of power for 10 hours. (120 watt/hours)

The 10 AH LiFePO4 battery is exactly the same size as our 9AH SLA battery. However, it contains 9% more energy and is 1/3 the weight of the SLA battery.

Our battery supplier states that the LiFePO4 battery can last up to 2500 charge / discharge cycles. The SLA batteries generally last 200-300 cycles. Therefore the life expectancy is approximately 10 times that of SLA batteries.

Excepting the battery chargers, all of GPAC's Portable Power Solutions accessories will work with the new LiFePO4 packs. The charge cycle of the new pack is different from the SLA charger cycle, therefore the SLA charger is not recommended for use with the new pack.

LiFePO4 batteries can be fully charged in less than half the time of SLA batteries

Model 1218 12 Volt 18 Amp Hour Pack

The 1218 features 2 fused 20 amp outputs with Anderson Power Pole connectors and a 18 amp hour battery. Like the 1209 it shares all of the same features with the exception of battery capacity and size.

The 1218 weighs approximately 12 pounds, yet is easily transported due to the soft grip handle.

The pack can deliver 24 watts of power for 9 hours. (216 watt/hours)

The 18 Amp Hour battery has plenty of reserve capacity and is the right choice for most Total Stations. For example, a Trimble 5600 will run 15 hours in Autolock mode or 10 hours in Robotic mode with a single charge.

The supplied charger (included in the complete package) will recharge the battery in 9 hours or less.

Model 1235 12 Volt 35 Amp Hour Pack

The Model 1235 features 2 - 12 volt 20 amp fused outputs with Anderson Power Poles and 1 SAE 2-pin covered connector fused at 20 amps.

This pack is designed for use as a base radio power supply. The pack can deliver approximately 46.7 watts of power for 9 hours. (420 watt/hours)

For example the pack can run a Pacific Crest HPB PDL or RFM96W 35 watt base radio and the GPS receiver for about 4 hours with the Hi/Low power switch set to the Hi Power position. (35 watt output).

Multiple packs can be plugged together to increase the amp hour rating.

The complete pack with power cable, battery and accessories weighs approximately 25 pounds.

Model 1250 12 Volt 50 Amp Hour Pack

The Model 1250, 12 volt 50 amp hour pack features 2 - 20 amp fused outputs with Anderson Power Pole connectors.

The 1250 weighs approximately 13 pounds.

The pack can deliver 12 watts of power for 50 hours. (600 watt/hours)

The 50 AH LiFePO4 battery is half the weight of our 35 AH battery pack. However, it contains 43% more energy than our 35 AH SLA battery.

Our battery supplier states that the LiFePO4 battery can last up to 2500 charge / discharge cycles. The SLA batteries generally last 200-300 cycles. Therefore the life expectancy is approximately 10 times that of SLA batteries.

Excepting the battery chargers, all of GPAC's Portable Power Solutions accessories will work with the new LiFePO4 packs. The charge cycle of the new pack is different from the SLA charger cycle, therefore the SLA charger is not recommended for use with the new pack.

LiFePO4 batteries can be fully charged in less than half the time of SLA batteries
