Its 0-30V adjustable voltage range and 0-5A adjustable current capability allow users to change test parameters rather than working with a fixed DC source.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003e3-Digit DC Test Power Supply\u003c\/strong\u003e format provides a direct numerical reference during bench work, while the \u003cstrong\u003eEncoder Adjustment\u003c\/strong\u003e makes repeated voltage and current changes more convenient. The 10mV voltage setting resolution and 1mA current setting resolution further support controlled adjustment when comparing components or checking a circuit at different operating points.\u003c\/p\u003e\n\u003cp\u003eWith its 150W rated power and compact mini form factor, the SPS-E305 can fit into component evaluation benches, electronics repair stations, educational laboratories, and prototype development environments. It is a practical choice for users who need an \u003cstrong\u003eAdjustable DC Power Supply\u003c\/strong\u003e for component evaluation without requiring a larger bench power system.\u003c\/p\u003e","brand":"Shenzhen Kuaiqu Electronic Co., Ltd","offers":[{"title":"SPS-E305","offer_id":47971870113969,"sku":"SPS-E305-B-K-0924-04","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/8027\/3329\/files\/3-Digit_DC_Test_Power_Supply_NICE-POWER_SPS-E305_30V_5A_150W_for_Electronic_Component_Testing-01.png?v=1790239975","url":"https:\/\/www.kuaiquinstrument.com\/es\/products\/3-digit-dc-test-power-supply-nice-power-sps-e305-30v-5a-150w-for-electronic-component-testing","provider":"KUAIQU Instrument Store","version":"1.0","type":"link"}
