  • DC-3VA - Two Channel DC Voltage and DC Current Logger This portable data logger is ideal for monitoring and recording one, two channels of DC voltages from up to 300Vdc and one channel of DC currents on either a 10A scale or 100A scale; for example from batteries, circuit breaker trip batteries, charging circuits, power supplies, photovoltaic (PV) cells, DC motor circuits, DC Generators, DC telecoms circuits. All Electrocorders use a constant sampling technique, meaning they sample every cycle multiple times, missing very little data! Many, many other brands do not, they simply sleep for 99.99% of the time, waken to take a sample, then sleep; they miss 99.99% of the data! How can you perform a survey when 99.99% of the data is missing? DC-3VA-IP43-KIT includes logger (1), fused voltage input leads (3), EC-CP100 DC Current Probe (1), USB lead (1), 12Vdc PSU (1), software (1) and carry case (1).

  • CT-3500 S2 - Digital Circuit Breaker Analyzer The CT-3500 S2 is Vanguard’s second generation, stand-alone, digital, microprocessor-controlled, circuit-breaker timer. It measures the elapsed time from the instant a breaker coil is energized to the instant of opening or closing of a circuit-breaker’s dry contacts. In addition to timing a breaker’s contact response time, the CT-3500 S2 can also time relays or other switching functions that use an initiating trigger voltage (24-300 Volts DC or AC).
