44 – 97 VDC

48V–72V packs — motorcycles, golf carts, small EVs

TDC-IY-108-12

74 – 162 VDC

96V–144V packs — classic car conversions, small trucks

TDC-IY-144-12

103 – 227 VDC

120V–200V packs — mid-range EV conversions

TDC-IY-320-12

206 – 454 VDC

300V–400V+ packs — Tesla-class, commercial, industrial

Why builders choose the Elcon 1000W

  • 94%+ conversion efficiency — minimal energy lost as heat, extending driving range and reducing thermal management needs.
  • 72A continuous / 88A peak — handles headlights, ECUs, water pumps, fans, infotainment, and power steering simultaneously.
  • Automatic 12V battery management — connect directly to your auxiliary battery; maintains charge state like a traditional alternator.
  • IP67 sealed & fully potted — waterproof, dust-proof, vibration-resistant; mount it anywhere on the vehicle.
  • No fans, no maintenance — passive aluminum heat dissipation with over-temperature derating at 85°C and auto-shutdown at 90°C with self-recovery.
  • CAN bus ready — optional CAN wiring for enable/disable control via your VCU or BMS (250kbps default, 500kbps on request).
  • Parallel capable — run two units for 2kW+ / 144A systems (dedicated output cables required per unit).
  • Wide operating range — −40°C to +65°C handles arctic cold starts and desert engine bays.

Built for demanding applications

EV Conversions

Classic cars, trucks, vans — power all 12V accessories from your high-voltage lithium pack.

Electric Motorcycles

Compact enough for two-wheelers. Use TDC-IY-72-12 for typical 48V–72V packs.

Marine & Boat Conversions

IP67 rating handles bilge-level moisture and salt spray environments.

Golf Carts & UTVs

Lithium upgrade projects needing reliable 12V accessory power from 48V–72V packs.

Commercial Fleet

Last-mile delivery vans, shuttle buses, and medium-duty electric trucks.

Off-Grid & Industrial

Step down high-voltage battery banks to power 12V DC loads, monitoring, and forklifts.

Installation Notes

Mount using the four-bolt pattern (4.25 × 8.75 in) in any orientation. While IP67 permits fully exposed mounting, positioning with natural air circulation improves thermal performance under sustained loads. Connect high-voltage input, 12V output, and 12V enable signal (to ignition switch or VCU). Fuse both HV input and 12V output circuits.

⚠ Parallel wiring: When running two converters in parallel, each unit must have its own separate 6 AWG output cables running individually to the battery or load. Do NOT combine output wires into a single heavier conductor before reaching the load. Use equal cable lengths for balanced current sharing.
CAN bus (optional): Connect CAN-H and CAN-L to your vehicle's CAN bus with proper 120Ω termination at both ends. Ships at 250kbps; 500kbps available on request.

FAQs

How do I choose the right input voltage model?

Select the model whose input range fully covers your pack's operating voltage from lowest SOC to peak charge. For example, a 96V nominal pack (~80V–115V) fits the TDC-IY-108-12 (74–162V). A 350V Tesla-module pack fits the TDC-IY-320-12 (206–454V).

Can I run two converters in parallel for more power?

Yes. Each converter must have its own separate 6 AWG output cables (equal length) running individually to the load. Do not combine into a single cable before the load.

Is this converter waterproof?

Yes. IP67 — completely dust-tight and withstands temporary submersion to 1 meter for 30 minutes. Fully potted for vibration and shock resistance. Suitable for underbody, engine bay, and marine mounting.

Does it automatically charge my 12V auxiliary battery?

Yes. Connect the output directly to your 12V battery. The converter regulates at 14.0V and manages the charge state automatically — similar to a traditional alternator.

Does it need a fan or active cooling?

No. Passive cooling only. At 94% efficiency, heat output is ~60W at full load. Built-in thermal protection derates at 85°C and shuts down at 90°C with automatic recovery.

What does the CAN bus option do?

The optional CAN wiring allows enable/disable control via CAN commands (in addition to the 12V enable input). Useful for integration with a VCU or BMS. Default 250kbps, 500kbps on request.

What wire gauge for the 12V output?

6 AWG for a single converter at full 72A. Keep runs as short as practical. For parallel setups, each unit gets its own dedicated 6 AWG pair.
