  • Circuit Breakers
    . On ac, the impedance changes as an iron core moves into the coil. Hydraulic-magnetic breakers have a different ampere-turn ratio for ac than for dc; thus, they should be used on their respective types of current. This is also true of 400 and 60-Hz breakers. An instantaneous circuit breaker responds...
  • DC Motor Trouble-Shooting Chart
    : Fuse or circuit breaker is tripped. Replace the fuse or reset the breaker. Armature is shorted or went to ground. Motor may make a humming noise and the circuit breaker or fuse will trip. Disassemble motor and inspect the armature for a burnt coil. Inspect the commutator for burnt bars...
  • What Does "Equalize" Charging Do, and Why is it Needed?
    charger. Q: If the input circuit breaker of the charger is 70 Amps, can the contractor install a smaller circuit breaker in his panel based on the 49.2 Amps input current of the charger?. Q: One of my customers needs a charger to operate in a -40C ambient. Which of your units will do this?. Q...
  • Secure Power with Next Generation SPDUs (.pdf)
    . Output voltage. use since the mid-1980s and are designed to. (Control er Area Network) standard. Presence or absence of load. replace thermal/mechanical circuit breaker. (at no extra cost). Switch failure mode (open or. and relay systems. By using low-level electri- ARINC 429 and Mil-Std-1553 data...
  • How to Set Up an Isolation Transformer with Balanced AC Output for Your Home Theatre Components
    ground might be 2 Volts. This is due to the fact that the neutral leg is attached to ground back at the circuit breaker box, but is not at zero potential by the time you get to the AC wall socket. The neutral is the return leg for the current, and because it has some resistance, the voltage is not zero...
  • Megger- A Guide to Low Resistance Testing
    : Resistance (R) = Voltage (E) / Current (I) At that time, the standards for Voltage, Current and Resistance had not been developed. Ohm's Law expressed the fact that the magnitude of the current flowing in a circuit depended directly on the electrical forces or pressure and inversely on a property...
  • Smart Computing Article - Basic Troubleshooting- Power Supplies
    suddenly stops working, starts to generate errors, or randomly shuts down (especially after you install a new device), the PSU should be one of the first suspects on your list. Technically, what we call a power supply is actually a switching transformer. It transforms AC (alternating current) into DC...
  • What is the Correct Charging Voltage?
    says that the 70A breaker SENS installed is too big for the 49.2A input current rating on your charger. Q: If the input circuit breaker of the charger is 70 Amps, can the contractor install a smaller circuit breaker in his panel based on the 49.2 Amps input current of the charger?. Q: One of my...
  • How are "Equalize", "Boost" and "Fast Charge" Charging Different?
    chargers are CSA compliant?. back to top. Charger operating environment. Q: When is it OK to run a 50 Hz charger on 60 Hz AC and vice-versa?. Q: The site inspector says that the 70A breaker SENS installed is too big for the 49.2A input current rating on your charger. Q: If the input circuit breaker...
