Harald Charger

The JH TEKNIK Harald Charger is an industrial-grade intelligent battery charger engineered specifically for professional underwater communication consoles, including the Diver Phone series. Optimized for the internal 12V Sealed Lead-Acid (SLA) or Gel batteries used in commercial diving surface stations, this charger features a precise three-stage charging control circuit that automatically detects battery status and adjusts output currents accordingly. Housed in a heavy-duty, dustproof, and high-dissipation casing, the Harald Charger is built to withstand rigorous maritime, vessel, and field-station environments, delivering fast, safe, and battery-preserving charging to ensure subsea life-safety communications are always fully powered.

  • Intelligent Three-Stage Charging: Features automatic switching between Constant Current, Constant Voltage, and Float Charge stages to prevent overcharging, gassing, and dry-out, vastly extending internal SLA battery lifespans.
  • Multi-Level Electrical Protection: Built-in protection against output short-circuits, reverse polarity connection, and over-temperature thermal cut-back, ensuring risk-free operation in demanding marine environments.
  • Universal Global Voltage Input: Supports 110-230 VAC wide-range AC power input, enabling stable charging performance from municipal grids, mobile generators, or vessel auxiliary power generators alike.

Scope of Application

  • Commercial diving contractor equipment bays, facilitating daily charging maintenance and battery preservation of Diver Phone consoles
  • Municipal fire departments and search & rescue dive squads, prepping portable SCUBA wired intercom units for rapid deployment
  • Oceanographic research vessels and offshore wind fleet support ships, securing auxiliary deck-console backup battery charging
  • Naval combat swimmer depots, special force logistics support, and tactical subsea salvaging power management

The Intelligent Sentinel for Uninterrupted Diving Coms JH TEKNIK Harald Charger Professional Dive-Phone Charger

  • Pre-Mission Emergency Prep: Charges portable diving telephones rapidly and safely before rapid deployments, ensuring uninterrupted coms on-scene.
  • Vessel Deck Power Conditioning: Provides surge protection and voltage stabilization under fluctuating ship auxiliary generators, charging units safely.
  • Off-Season Storage Float-Charge: Sustains micro-current float charging during off-season storage, preventing subsea console batteries from self-discharging and dying.

Value&Benefits

In severe commercial diving environments, the health of the 12V SLA battery decides whether vital voice links stay connected. The JH TEKNIK Harald Charger is more than a simple battery charger; it is the life support of your subsea communication network, adjusting charging curves through microprocessors to prevent battery swelling in high-humidity, high-salinity zones.

  • Maximizes Asset Lifespan: Prevents lead-acid battery sulfation and bulging, boosting the internal battery life of your Diver Phone by multiple folds to lower replacement costs.
  • Eliminates Human Error Hazards: Plug-and-play design with reverse polarity protection prevents charger or console burnouts even when operators connect poles incorrectly in dark, rushed fields.
  • Accelerates Mission Readiness: Highly efficient charge curve minimizes downtime between diving operations, boosting daily diving fleet turnaround efficiency.

Performance

  • Dual-color high-visibility LED indicator (Red for charging, Green for fully charged/float mode) offers effortless visual tracking from a distance.
  • Heavy-duty connector perfectly matches the proprietary charging sockets of JH TEKNIK boxes, preventing accidental unplugging.
  • Sealed enclosure safeguards internal electronics against sea spray and corrosive vapors, utilizing conformal coating on the circuit boards for extra moisture protection.
