Import Dps-305 Adjustable Dc Power Supply — Buy in wholesale FOB from Supplier in China

The DPS-305 Adjustable DC Power Supply is a digital‑input, LED‑display unit designed for precise voltage and current regulation. It accepts 110 V or 220 V AC input at 50/60 Hz and delivers a continuously adjustable output from 0 V to 30 V with a maximum current of 5 A. Three model variants are listed: DPS‑305BM with a four‑digit voltage display and 0.001 A current resolution, DPS‑305BF with a five‑digit display and 0.0001 A resolution, and DPS‑305CF adding memory storage and password lock functions. The unit measures 265 mm × 128 mm × 150 mm (L × W × H) and is rated for operation between 0 °C and 40 °C and 20 %‑80 % relative humidity.

Internally the supply uses an electronic switch to enable rapid load connection and includes a voltage stability of ±0.1 V, voltage ripple of 1 mV RMS (5 Hz - 1 MHz), and a temperature coefficient of 300 ppm/°C, which meet typical laboratory‑grade performance. The constant‑current mode provides adjustable current up to 5 A with a resolution of 0.01 A and a stability of ±0.01 A plus 3 mA load variation, matching standard bench‑power specifications. Typical industry expectations for a bench power supply of this class include overload protection, short‑circuit protection, and compliance with IEC 60950‑1 safety standards, which are commonly offered though not explicitly certified by the supplier. The device also features a sound alarm for over‑voltage or over‑current conditions and a quick‑call memory for ten preset voltage/current pairs, facilitating repeatable test setups.

This power supply is frequently employed by mobile‑phone repair shops, electronics hobbyists, and small R&D labs that require accurate, programmable DC output. Buyers should request confirmation of the model code, included accessories such as the 44‑piece power conversion cable set, and any applicable safety certification before placing an order. The supplier lists the product as ready for bulk shipment from Shenzhen, China, but does not disclose minimum order quantity, lead time, Incoterms or payment terms, all of which must be clarified with the seller. Packaging is described as individual units, and the supplier can arrange palletised cartons on request, a detail that should be verified during negotiation.

Shenzhen Weikexiu Technology Co., Ltd. is located in Juguang E‑Commerce Industrial Park, Building 8, No. 9 Qilin Road, Bantian Street, Longgang District, Shenzhen, 518116, China. The company is listed under the “harbor” verification tier, indicating that basic business registration information has been validated. Its response rate is currently recorded as 0 %, and average response time is not available, suggesting that communication may require proactive follow‑up.

The firm markets electronic test equipment, including the DPS‑305 series adjustable DC power supplies, and lists the product with detailed technical parameters but does not provide explicit certifications, MOQ or lead‑time details. Potential buyers should note that the supplier’s profile does not mention export experience or third‑party audit results, so additional due diligence is advisable before committing to a purchase.
