The Pulsar with electronic fuse saver, from Innovative Products of America, finds short circuits, open circuits, faulty electrical equipment and parasitic draw. It allows for safe bench testing, reading amperage and aftermarket equipment setup. Plug the Pulsar into a fuse box, dial in the desired fuse limit and the Pulsar’s internal computer safely monitors the circuit while displaying amperage. If a short is present, the Pulsar automatically pulses power while protecting the circuit. Pulsar is an automatic circuit breaker, adjustable fuse, voltage probe, fuse saver and amp reader in one. Range is 100 mA – 50 amps.
