DC UPS

A DC UPS is an uninterruptible power supply that outputs direct current. That distinction matters because most small network devices run on DC already: a router, a modem, a CCTV camera, and an optical network unit each take DC from a power adapter that converts mains AC to the DC the device needs. A DC UPS replaces that adapter in the chain, delivering DC directly from the mains when it is present and from its battery when it is not, without the extra conversion step that an AC UPS would add. For small devices, that directness is the point: fewer conversions, less waste, and a smaller unit.

Richroc's range sits in this DC category, as its marketplace listings describe DC output for routers, modems, and cameras. The DC UPS pages on this site therefore cover the same products as the mini UPS pages, viewed from the technical side rather than the application side. The category distinction is useful for buyers who search by technology rather than by device: a buyer who knows the load is DC and wants a DC solution can start here, while a buyer who knows the device but not its power type can start from the application pages. Both routes lead to the same inquiry, where the voltage and load are confirmed for a real order.

Voltage is the central technical question for DC UPS, and the voltage guides treat it in general terms. Common outputs for small network devices include 5V, 9V, and 12V, and some setups need 24V or 48V for larger or longer-run equipment. Those figures appear in listing titles and in search terms, and this site treats them as general knowledge about device voltages, not as published specifications for a named model. The rule for any buyer is the same: read the device label, match the output, and confirm the total current draw before ordering.

Multi-output DC UPS units deserve a separate note, because they solve the most common DC problem: a setup with several devices at different voltages. A router at 12V, a modem at 9V, and a camera at 12V cannot share a single-voltage output, but a multi-output unit can serve them together from one battery. The multi-output page explains how to add up the devices and check the total draw, and the router and modem continuity guide explains why protecting the whole chain matters. As elsewhere on this site, no multi-output configuration is presented as a named model's specification; configurations are discussed per order.

DC UPS and DC-DC conversion are related but different topics, and this site keeps them apart. A DC UPS provides battery backup for DC devices. A DC-DC converter changes one DC voltage to another without battery backup. A buyer who needs both should say so in the inquiry, because the products are different even though the vocabulary overlaps. The guides on this site use the UPS term only for backup products, and do not borrow converter specifications for UPS pages.

For quantity buyers, the inquiry route applies as throughout the site. Minimum order quantity is confirmed per order, customisation can be discussed, certificates are available upon request, and delivery time is not published. The company contact is Ms. Zita Huang, and the contact page carries the inquiry form. No telephone number, email address, or street address is published pending verification.
