What does it really cost to run that electric water heater or energy-efficient refrigerator? Find out instantly by plugging it or any other electrical appliance into Watts Up? PRO ES, which instantaneously displays the wattage being used, as well as the cost, in actual dollars and cents! The Watts Up? PRO ES measures voltage and current information thousands of times a second, yet is simple to use. Only six values are displayed in the main modes. Additional information is available in the detail mode. Clear English wording on the LCD is used to describe what is displayed. The Watts Up? PRO ES has an incredibly fast response time, enabling you to "see the surge" of power when appliances are first turned on. Input is via a 6' electric cord, output is via an outlet on top of meter. The peak value display captures this surge so it's displayed even if it happens too fast to see live.

MOSFET drivers in a voltage and current gain circuit.
1 second turn-on delay.

Fault protected outputs.
Electricity usage monitor connects to appliances and assesses efficiency. Large LCD display counts consumption by the kilowatt-hour. Calculates electricity expenses by the day, week, month, or year. Displays volts, amps, and wattage within 0.2 percent accuracy. Compatible with inverters; designed for use with AC 115-volt appliances. The RA200 features two 100 watt RMS - 4 ohm outputs, a bridging switch, MOSFET drivers in a voltage and current gain circuit, one second power-up delay, and LED power output meters. The unit is housed in a painted steel chassis and includes a special high performance transformer and a fused power line. The MOSFET output stage is fault protected which allows the RA200 to forgive momentary output shorts, and has over-temperature protection. CAUTION The RA200 is convection cooled. Adequate ventilation room for the heat sink fins on the rear panel must be provided.
