Robot Power Simple-H Dual Channel H-Bridge Controller 20A, 5-28V for 3-5V Logic
Drives motors up to 28V
Handles 20A continuous output
Supports up to 25A with fan
Integrates with standard systems
Features built-in current limiting
The Robot Power Simple-H Dual Channel H-Bridge Controller 20A, 5-28V for 3-5V Logic is a versatile and robust circuit designed for driving DC motors and other DC loads within a range of 6V to 28V. It supports a wide array of command sources, from simple switches to complex microcontrollers, making it adaptable for various applications. The controller requires external signal sources to translate command inputs into the necessary switching signals, offering flexibility in its operation.
This controller is distinguished by its ability to handle continuous output currents of up to 20A, with the potential to reach 25A when equipped with an optional cooling fan. It is engineered to maintain its current ratings over extended periods, unlike many competing products that only sustain high currents for brief durations. The Simple-H's design includes heatsinks and heavy copper areas on the circuit board to efficiently dissipate heat, ensuring reliable performance.
The Simple-H HV variant allows for input signals up to 28V, with indicator LEDs that maintain consistent output regardless of signal voltage. This feature enables direct control using switches from 12V or 24V battery sources without the need for additional voltage regulation. The controller's construction supports easy integration with existing systems, featuring a standard screw terminal for command and status connections, and the option to configure as a single full H-bridge or two independent half-bridge circuits. Note: Ensure proper heat dissipation to maintain optimal performance and prevent overheating.

Fairly straight forward. Instructions decent but didn't really mention the Enable Pin which threw me for a while. Got it working and works great with my linear actuator going in both directions.

Nice and easy to use
Great and simple design. I would like to have a status LED indicating when there is power connected.

Nice et facile à utiliser
Design simple et génial. J'aimerais avoir un voyant d'état indiquant quand le courant est connecté.

Excellent tableau de bord haute puissance
Assez simple. Les instructions étaient correctes mais ne mentionnaient pas vraiment le code d'activation qui m'a lancé pendant un moment. Il fonctionne parfaitement avec mon actionneur linéaire dans les deux sens.

A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
