The Jetfon PC-1335 switching power supply delivers a continuous 13.8 V DC regulated output with a robust 30 A maximum current capability, engineered specifically for mission-critical two-way radio base stations, repeaters, and telecommunications equipment. Equipped with an integrated backup battery charger and instantaneous automatic UPS switching functionality, it prevents service disruptions and maintains continuous operation during unexpected AC mains power outages.
Featuring an efficient, low-noise switching architecture (ripple and noise ≤ 100 mVp-p) and tight voltage regulation (< 2%), the PC-1335 eliminates background hum and RF interference in transmission lines. Its rear panel features a versatile three-terminal layout (one shared common negative terminal and two positive terminals) to power communication equipment while concurrently keeping an external 12 V backup battery charged. Complete with built-in short-circuit, overload, and overvoltage protections, it delivers industrial-grade reliability in a lightweight, compact footprint (1.52 kg).
Key Advantages
- Uninterrupted Operation: Instantaneous, seamless automatic switchover to a connected 12 V battery during AC mains power failures.
- Comprehensive Equipment Protection: Automatic safeguards protect connected electronics against short circuits, overloads, and overvoltage spikes.
- Clean RF Performance: Ultra-low ripple and noise (≤ 100 mVp-p) minimize transmission artifacts and receiver hum.
- Compact Form Factor: Lightweight design (1.52 kg) with included mounting brackets saves valuable desk and rack space.
- Flexible Three-Terminal Terminal Block: Simplifies concurrent connection of load equipment and external backup batteries.

Frequently Asked Questions
How does the automatic battery backup switchover operate?
When an external 12 V rechargeable battery is wired to the designated terminal, the unit powers the load while float-charging the battery. If AC mains power fails, the system instantly switches to battery power without interruption. Once AC mains power is restored, the unit seamlessly resumes powering the radio and begins recharging the battery.
Can lithium-ion (Li-Ion) batteries be used with the PC-1335?
No. The backup charging circuitry is calibrated strictly for standard 12 V Lead-Acid, AGM, and Gel chemistries. It is not compatible with Lithium-Ion battery packs.
