The GW Instek GPR-1810HD is a single-output 180 W linear DC power supply from the GPR-M Series, providing 0–18 V and 0–10 A of continuously adjustable output. Built on the same architectural platform as the higher-power GPR-H Series, the GPR-M Series is positioned for high-end precision benchtop applications where lower total power is sufficient but tight regulation and low output noise remain priorities.

A linear DC power supply provides controlled, regulated direct-current voltage and current to a device under test. Linear regulator topologies are typically chosen over switching designs when output noise and ripple need to be minimized — for example when powering precision analog circuitry, low-level sensors, RF front ends, or audio stages where supply noise would couple directly into the signal path. The GPR-1810HD's continuously adjustable voltage and current ranges, combined with automatic constant-voltage / constant-current crossover, let an engineer set both a target voltage and a current limit so the supply protects the DUT against overcurrent conditions during development and bring-up.

ValueTronics stocks the GPR-1810HD and the rest of the GPR-M family in our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, where every {{CONDITION}} unit is handled by our own staff rather than passed through to a drop-ship partner. Operating from a single facility lets us verify what's actually in stock before quoting, control how each instrument is inspected and packaged, and answer technical and order-status questions directly rather than routing them back to a manufacturer.

## Brand Heritage

GW Instek is the test and measurement brand of Good Will Instrument Co., Ltd., a Taiwanese manufacturer founded in 1975. The company has operated continuously under the same corporate identity, with no major acquisitions or rebrands affecting its T&M product lines.

## Compare Other Models in This Series

The GPR-M Series comprises three 180 W single-output linear DC power supplies that share an identical feature set — regulation, ripple, noise, metering, protection, and chassis — and differ only in how the 180 W output envelope is distributed between voltage and current. The GPR-1810HD provides 0–18 V at 0–10 A, the GPR-3060D provides 0–30 V at 0–6 A, and the GPR-6030D provides 0–60 V at 0–3 A.

Because the underlying electrical design is consistent across the family, model selection within the GPR-M Series is primarily a question of matching the supply's voltage and current envelope to the device under test rather than a question of feature tier. A bench that needs to source 8 A at 12 V is a GPR-1810HD application; a bench that needs to source 5 V at small current alongside a separate 48 V rail is a different conversation entirely.

Each model below links to its own pre-owned product page with condition-matched pricing, accessories list, and current availability. Pricing and lead time for pre-owned GPR-M units depend on which specific model and condition tier is selected, and on what's currently in stock at the time of quote.

Within the GPR-M family, the GPR-1810HD is the high-current, lower-voltage configuration: its 0–18 V range covers most logic-level and low-voltage analog rails (3.3 V, 5 V, 12 V, 15 V), and its 0–10 A current capacity gives meaningful headroom for loads that draw several amps continuously or have inrush events at startup. Customers selecting between GPR-M models on the basis of current capacity rather than maximum voltage will land on the GPR-1810HD.

The three GPR-M models partition the same 180 W envelope differently. The GPR-1810HD trades maximum voltage for maximum current (18 V / 10 A); the GPR-3060D balances both (30 V / 6 A); the GPR-6030D trades current for maximum voltage (60 V / 3 A). The comparison table below summarizes the voltage and current ranges across the family — outside of those two numbers, the specifications are common to all three units.

Practical selection guidance: identify the highest voltage the DUT requires, then confirm that the chosen model's current capacity at that voltage covers steady-state draw plus inrush margin. Customers whose work spans more than one of these envelopes sometimes specify two GPR-M units on the same bench rather than compromising on either rail.
