Schumacher DSR140 200/50/25/10 Amp 12/24V Manual Wheel Charger

PROFESSIONAL GRADE: Powerful engine starter boasts 200 cranking amps (12V), which packs enough power to start cars, SUVs, trucks, boats, and other large engines.
50A 12V AND 25A 12V/24V BOOST MODES: The boost modes quickly bring deeply discharged batteries back to life.
PRECISION CONTROL: A 135-minute manual timer gives the user exacting control over the entire charging process.
WORKS WITH MANY BATTERY TYPES: The DSR140 is compatible with 12V and 24V standard, AGM, gel, and deep-cycle batteries.
EASY-TO-READ METER: Visually monitor charging levels with the built-in analog ammeter.

The DC voltage and ammeter can display the measured DC voltage and DC current simultaneously on the same meter screen..
Wide measurement voltage and current range, DC Voltage: DC0-199.9V.
The measured DC voltage and DC current are completely isolated within the meter..
Suitable for chargers, inverters, solar energy, wind driven generator, LED light measurement, etc..

MFJ-931 creates an artificial RF ground! It resonates a random length of wire thrown along the floor and produces a tuned counterpoise. This ground effectively places your rig near actual earth ground potential even if your rig is on the second floor or higher with no earth ground possible..
Also, the MFJ-931 electrically places a far away RF ground directly at your rig -- no matter how far away it is. It reduces the electrical length of the ground connection wire to virtually zero by tuning out its reactance..
The MFJ-931 connects between your rig and a random length of wire or a connecting ground wire. Its tuned for maximum ground current using the built-in RF ammeter. The MFJ-931 Artificial RF Ground covers 1.8 - 30 MHz and measures a compact 7.5W x 3.5H x 7D inches..

Compact, portable and lightweight design.
Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.
Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.
Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.

Measures 0 to 60 Volts. Works on 12, 24, 36, and 48 volt battery bank systems..
Precision Alu-Chrom current sensing resistor, with only 0.001 Ohms resistance and circuitry that draws only 7 mA..
This is the All-In-One Meter:a power meter, a volt meter, an amp-hour meter, ammeter and energy meter.Digital LCD screen gives clear crisp number readings..
Perfect troubleshooting tool:it's indispensable for analyzing, testing and troubleshooting any DIY DC power project..
Professional RC Watt Meter is an excellent addition to your RC hobby, DC circuits, Solar system, Boat/RV & Battery Backup systems!.
