Imtra DMS Universal LED PWM Dimmer, 6-30VDC, 0-10V Input

Overview

The Imtra DMS Series is a universal low-voltage LED dimmer that uses pulse width modulation (PWM) to provide smooth, flicker-free brightness control for marine lighting circuits. Operating from a 6-30VDC power supply, it supports dimmable 12V and 24V LED bulbs, flexible and rigid LED strips, and compatible low-voltage halogen and incandescent lamps.

The dimmer accepts several control methods, including momentary switches, potentiometers, and 0-10V control signals. Its adjustable minimum brightness setting allows the dimming range to be tailored to the connected lighting, while built-in electrical protections help manage overload, overheating, and short-circuit conditions.

Key features

• 6-30VDC input voltage range for low-voltage DC lighting systems.

• High-frequency PWM control with a 0-100% dimming range.

• Supports compatible 12V and 24V LED, halogen, and incandescent lighting.

• Accepts momentary push-button, potentiometer, and 0-10V control inputs.

• Adjustable minimum brightness level.

• Overload, overheating, and short-circuit protection.

• Multiple dimmer modules can be synchronized for larger lighting loads.

• Compact 96 x 40 x 20 mm housing with screw-terminal connections.

Variants

The DMS Series is available in two configurations with different electrical load ratings.

Both configurations share the same operating voltage range, PWM dimming functionality, and control options. The load rating determines the maximum current capacity of the connected lighting circuit.

• ILDMS-850-X, Load Rating 8.55A: Higher-current configuration for lighting circuits requiring greater load capacity.

• ILDMS-500-X, Load Rating 5A: Lower-current configuration for lighting circuits within the 5A load limit.

Installation and control

The dimmer connects to the DC power supply, lighting load, and selected control interface through screw terminals accommodating conductors up to 2 mm2 (14 AWG). Control arrangements include single momentary switching, separate up/down momentary switches, potentiometer control, and integration with compatible 0-10V control systems.

For installations with lighting loads exceeding the capacity of a single module, multiple DMS dimmers can be synchronized. The connected lighting must be compatible with PWM dimming, and the total circuit load must remain within the selected module's current rating.

Orders are processed within 2 business days, which includes verification, packing, and dispatch. Orders of $100 or more qualify for free shipping when eligible. For orders under $100, shipping costs are calculated at checkout based on destination, package weight, and selected service. International shipping is available for eligible products, and certain items may require additional handling, warehouse transfers, or may ship directly from the manufacturer, which can affect processing time.

Deliveries are handled by preferred carriers such as USPS, UPS, FedEx, DHL, and others depending on your location and selected service. Estimated delivery times are displayed at checkout and may vary due to customs processing, carrier delays, weather, postal disruptions, or other circumstances beyond our control. Once your order ships, you'll receive a confirmation email with tracking information. Tracking may take up to 24 hours to update on the carrier's website and is also available through your account when applicable.

We ship throughout the United States and to most international destinations for products eligible for international shipping. International orders may be subject to customs duties, taxes, brokerage charges, or other import fees, which are the customer's responsibility and are not included in the product or shipping price. PO Boxes are accepted only when shipping through USPS, and not all packages qualify for this option.

Returns may be requested within 30 days of receiving your order. Items must be unused, uninstalled, unaltered, and returned in their original packaging with all tags, packing materials, blank warranty cards, manuals, instructions, accessories, and included items. Certain products, including installed or used electronics, electrical components, lighting, consumables, custom or special-order items, cut-to-length products, safety equipment, and merchandise exposed to water or marine conditions, may not be eligible for return.

To request a return, sign in to your account and select the applicable order and items, and submit your request for review. Eligible unfulfilled items may also be submitted for cancellation within 1 hour of placing the order. Returns or cancellations are not considered approved until you receive confirmation from Apollo Lighting. Please do not ship or drop off merchandise before receiving return approval and instructions.

Customers are responsible for arranging and paying for return shipping unless the return is due to an error by Apollo Lighting or the item is verified as defective, damaged, or incorrect. Missing, damaged, defective, or incorrect items must be reported within 2 business days of delivery, and photos or other documentation may be required for review. If the issue is verified, Apollo Lighting may provide or reimburse return shipping and issue a replacement or refund depending on the circumstances. International customers are responsible for return shipping, duties, taxes, customs charges, brokerage fees, and other costs associated with an international return.

After your return is received and inspected, approved refunds are issued to the original payment method and may take 5-7 business days to appear after processing. Original shipping and handling charges are nonrefundable, and the value of any included free items that are not returned may be deducted from the refund. Apollo Lighting does not charge a standard restocking fee on eligible returns. Returns that are incomplete, damaged, installed, used, altered, improperly packaged, or otherwise do not meet the eligibility requirements may be refused. We recommend using a trackable and appropriately insured shipping service for all customer-arranged returns.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
