Product Description

Founded in 2005, Aurora Design entered into the vintage electronics industry at full speed. Offering fully functional automotive and radio products designed using OEM standards, Aurora Design ensures you can enjoy modern conveniences in your classic vehicle. Geared towards Delco® Wonderbar® radios manufactured in the late 1950's, the FMR-HV1 High Voltage Relay Driver supports seek relays that require high voltage. Unlike many other relay drivers, the FMR-HV1 High Voltage Relay Driver contains both low and high impedance relays. This allows it to stabilize the differential current in and out of the relay.
 
When tuned to the AM station, many radios struggle to produce a clean signal. There can be static, distorted voices and instruments, and stations bleeding into one another. The FMR-HV1 High Voltage Relay Driver solves this issue using a 2MHz switching regulator that eliminates the noise.
 
How does it do this?
 
Height. Designed without the 20-40kHz frequency common to similar products, the frequency emitted by the FMR-HV1 is above the AM band, which eliminates interference. Whether you're listening to NPR or some other news station, the signal will be uninterrupted.
 
Built with long-term use in mind, the FMR-HV1 High Voltage Relay Driver's high impedance relays fully operate while placing little demand on the return spring. This is achieved through voltage created from a 52V open circuit output. Like other drivers, you don't want to spend your hard-earned money, or time, constantly repairing your radio.
 
To help you keep track of these tiny parts, the entire FMV1-HV1 fits in a small container with no attachments. Its user-friendly design allows you to place it anywhere within the radio and directwire it to the seek relay. These features lessen wiring mishaps, manual-reading, and increases efficiency.
 
Stamped with the excellence of Aurora Design, the FMR-HV1 High Voltage Relay Driver is built and designed at a USA ISO9001:2000 facility. Methodically matched to SAE specifications, the FMR-HV1 High Voltage Relay Driver is, as of this writing, in limited supply.
 
For high-quality radio, pick one up today.

The FMR-HV1 is used to power the high voltage seek relays used in many late 1950’s Delco® Wonderbar® radios. The FMR-HV1 is a current limited supply that works with both the low impedance and high impedance style relays. With it’s 52V open circuit output voltage, even the high impedance style relays will operate normally without having to weaken the return spring. Unlike competing supplies that operate at 20-40kHz causing noise across the AM band, the FMR-HV1 uses an automotive switching regulator operating at 2MHz. Since this frequency is above the AM band, the FMR-HV1 cannot interfere with AM reception. The FMR-HV1 is fully self contained and requires no external components. It is designed to wire directly between the FMR-1 and the seek relay. It’s ultra small size and high efficiency allow it to be easily mounted anywhere inside the radio. As with all Aurora Design products, the FMR-HV1 is designed to SAE specifications and designed and built in the USA at an ISO9001:2000 facility.
