Bonitron’s Model M3484 line filters are designed to be used in applications where power electronic devices experience problems from line harmonics, capacitor switching transients and DC drive notching. Typically, devices with these problems have overvoltage faults. The problems are more severe when the devices are in a standby or lightly loaded mode. For this reason, chokes alone are unable to filter the transients.
The Bonitron M3484 modules are composed of resistor, diode, and capacitive elements offering electrical damping of continuous and intermittent transients. (Each device includes 2 parallel filters, one for spikes and one for notches.) The transient/harmonic energy is dissipated in the resistors. The units are protected by a combination of fusing and thermal protection.
The filters require some impedance (at least 5%) between the noise source and their point of installation for proper filtering. Usually, existing AC chokes or system transformers provide this impedance. |
