OEM TENS Electro Stimulator | Dual-Channel Hardware | TOP-RANK
Dual-channel TENS electro stimulator for B2B procurement. Engineered with isolated transformer topologies and tactile interfaces for consistent pain gating protocols.
Product Overview
This electro stimulator is a baseline hardware platform for transcutaneous electrical nerve stimulation. It outputs low-voltage, asymmetrical biphasic square waves through physical lead wires. The dual-channel architecture permits simultaneous application across two distinct anatomical zones. We configure this specific PCBA and ABS housing combination for B2B pharmacy retail and clinical hardware distributors deploying high-volume, reliable pain management units.
Key Features
-
Transformer-Level Channel Isolation
If a user places Channel 1 electrodes on the left shoulder and Channel 2 on the right, non-isolated PCBA topologies allow stray electrical current to cross the chest cavity. This architecture deploys independent magnetic transformers for each output track. The electrical load on Channel 1 cannot physically bridge to Channel 2. The electrical vector remains strictly locked between the two specific hydrogel pads of the same lead wire.
-
Load-Compensated Constant Current
Skin resistance fluctuates continually due to sweat accumulation and pad pressure. A standard voltage-based machine causes the actual mA output to drop linearly as the hydrogel substrate dries out over a 30-minute session. This stimulator dynamically measures contact impedance at the epidermis. The internal boost circuit adjusts the voltage rail in real-time, locking the output to the exact milliampere selected by the user despite changes in the biological load.
-
Tactile Interface for Motor Impairment
Flat touchscreens fail when elderly users exhibit sweaty fingers or severe arthritis. This ABS housing prioritizes mechanical dome switches and analog amplitude dials. The physical actuation force requires deliberate pushing, providing direct haptic feedback. This structural design allows visually or motor-impaired patients to manually adjust the pulse width and intensity blindly, without navigating complex digital menus.
Applications
Post-Trauma Pain Gating
Sustained 80-100Hz output targeting acute nociceptive signal blockage.
Clinical Rehabilitation
Durable ABS housing withstands multi-patient turnover and drop impacts in physical therapy clinics.
OTC Pharmacy Retail
Packaged as a complete base kit with 2.0mm pin lead wires and hydrogel pads for at-home consumer use.

-
Regulatory: Technical files and electrical test data support OEM filings for CE (MDR) and FDA 510(k) Class II registrations.
FAQ
Q: Can we use a larger capacity battery to make the charge last a full month?
A: Expanding the Li-Po battery capacity requires altering the internal Z-axis clearance of the ABS casing. This mandates opening a new steel injection mold, which adds 30 to 45 days to the tooling timeline and increases the physical weight of the handheld unit.
Q: Why does the device shut off output when an electrode is unplugged?
A: The MCU continuously monitors the loop resistance. If the circuit detects an open loop (> 2000 Ohms), it drops the current to 0mA within milliseconds. This open-circuit protection prevents the user from receiving a sudden 100mA shock when the pad is re-applied to the skin.
