MFJ

Transceiver Voltage Conditioner

MFJ 4403 Transceiver Voltage Conditioners were designed to provide transceiver protection from even nonideal voltage sources which can cause major damage to radios and other equipment. This makes MFJ 4403 conditioners particularly valuable for DXpeditions, mobile and portable operation.

Even in the home, the MFJ 4403 provides protection from any potential power supply problems due to transients and noise induced on your transceiver’s DC input by any AC or RF anomalies.

Key Features

Even in the home, the MFJ 4403 provides protection from any potential power supply problems due to transients and noise induced on your transceiver’s DC input by any AC or RF anomalies.

• Reverse Polarity Protection – If you accidentally reverse your input voltage connection, the bright red REVERSE POLARITY LED will alert you to this fact with no damage to your equipment

• Transient Suppression – A heavyduty transient suppressor clamps input transients to 15 volts and handles over 200 amps peak current to protect your equipment from vehicle startup voltage spikes and poorly regulated power supply transients

• Short Circuit Protection – Input and output fuses instantly protect you from short circuit conditions. Automotive bladetype fuses are utilized for easy replacement

• Noise And Ripple Filtering – A capacitor bank consisting of over 4 Farads of capacitance filter off virtually all power supply noise and ripple. This capacitor bank provides enough power supply buffering that even poorly filtered and marginal power supplies can run your transceiver

• Rugged Construction Attractive allmetal cabinet and conservative component selection ensures solid performance for years to come

You don’t want to expose your transceiver to noise or ripple from your power supply. You certainly don’t want hum, hash or other DC supply noise on your transmitted signal!
