Wholesale 5 in 1 electric tricycle controller with DC converter

If you assemble electric tricycles or run a parts distribution business, you know the wiring headache: the motor controller in one box, the DC-DC converter in another, the headlight switch and horn relay in a third, plus an anti-theft alarm module with its own remote. Every additional component means more suppliers, more connectors, more failure points, and more labor hours on the assembly line. A typical cargo trike installation takes 40–50 minutes just for the electrical system, and wiring errors are one of the top three causes of warranty returns. At Xuzhou Kehuan Electrical & Mechanical Equipment Co., Ltd., we designed the EC-03 series to replace that stack of separate modules with a single integrated controller. Motor control, 12V DC conversion, headlight relay, horn driver, and alarm output — all in one housing, one harness, one set of labeled connectors. If you are looking for a 5 in 1 Electric Tricycle Controller with DC converter that cuts assembly time and reduces warranty cost, this is the part your production manager has been asking for.

Product Line Advantage: Universal Electric Trike Controller Integrated Light Horn Alarm

The EC-03 is the only controller in our lineup that consolidates five electrical subsystems into a single unit without compromising on current capacity or protection features. Competitors offer "all-in-one" units that top out at 35A — fine for a bicycle, not for a loaded cargo trike. Our EC-03 ships in 25A, 35A, 50A, 65A, and 80A variants, which means you can use the same integrated design from a light passenger trike up to a 1,500W cargo hauler. When you source a universal electric trike controller integrated light horn alarm from our factory, you get one part number, one supplier relationship, and one warranty chain instead of five.

 

 

— Voltage customization: 48V, 60V, 72V

— Current limit adjustment: factory-set or customer-specified

— DC output capacity: 10A standard, 15A on request for high-draw lighting

— Function enable/disable: each of the five functions can be activated or deactivated in firmware

— Wire harness length and connector type: configurable for your frame layout

— Speed limit, soft-start ramp, and regenerative braking: programmable

— OEM/ODM branding: label, packaging, and firmware version

— Minimum order: 50 units per SKU (mixed SKUs accepted)

— Tooling support available for large-volume customization (500+ units)

 

 

Client profile: A mid-size electric vehicle assembly plant in Dhaka, Bangladesh, producing approximately 1,200 cargo and passenger tricycles per year for the domestic market.

The problem: The plant sourced motor controllers, DC-DC converters, headlight switches, horn relays, and alarm modules from four different suppliers. Each vehicle required approximately 45 minutes of electrical assembly time, including crimping, soldering, and taping 18 separate wire joints. Quality inspection found wiring errors in 7% of vehicles, and warranty returns traced to electrical connection failures accounted for 8% of all after-sales claims. The purchasing team spent an estimated 25 hours per month managing four supplier relationships, four delivery schedules, and four MOQs.

 

The solution: The plant switched to our EC-03 60V 50A 5-in-1 integrated controllers for their entire passenger line and EC-03 72V 80A variants for their cargo line. We supplied custom 180 mm wire harnesses to match their frame routing and pre-configured the firmware with headlight and horn enabled, alarm disabled (their market preference). We provided a single GB/T 18488.2 test report covering all functions.

 

Results after 10 months in production:

— Electrical assembly time per vehicle: reduced from 45 minutes to 18 minutes (a 60% reduction)

— Wiring errors at quality inspection: dropped from 7% to 0.4%

— Warranty claims related to electrical connections: dropped from 8% to 0.5%

— Purchasing team supplier management time: reduced from 25 hours/month to 6 hours/month

— Component inventory value: reduced by 42% (eliminating separate converter, relay, and alarm stock)

— The plant expanded to a second shift in Year 2, citing simplified electrical assembly as a key enabler

This is what an all in one Electric vehicle controller supplier China is supposed to deliver — not just fewer parts, but faster assembly, lower warranty cost, and simpler operations.

 

 

Q1: Can I disable functions I do not need — for example, if my market does not require an alarm?

Yes. Each of the five functions — motor control, DC-DC converter, headlight, horn, and alarm — can be enabled or disabled in firmware before shipment. Simply tell us which functions you need active, and we configure the controller accordingly. The disabled functions are dormant; the wiring harness still includes the connectors, but no current is routed to them. If you want a physically smaller harness with only the active connectors, we can customize that for orders of 200+ units.

Q2: What is the minimum order quantity, and how do you handle mixed SKU orders?

Minimum order is 50 units per SKU. Mixed SKU orders (for example, 150 units split across 48V 35A passenger and 72V 80A cargo variants) are accepted with no surcharge. For orders of 500 units or more, we can assign a dedicated production batch and offer priority quality inspection. Sample orders of 5–10 units are available at standard unit price to allow pre-production testing.

Q3: What documentation can you provide for customs clearance and product compliance?

We provide the following as standard: ISO 9001:2015 certificate (English copy), GB/T 18488.2 test report, commercial invoice, packing list, and certificate of origin. If your import country requires additional documentation — such as CE marking support, RoHS declaration, or third-party inspection — please inform us at the inquiry stage. We have supported customers in the EU, Southeast Asia, Latin America, and Africa with documentation requirements.
