Comparison points and tradeoffs
When comparing Rectifier, Heavy-Duty 100 Amp, Compact Negative Base Replacement for Century, Solar and Other Negative Base Chargers with other Rectifiers options, use this source-backed detail as the primary discriminator: Category: Replacement Parts / Starters & Alternators / Alternators & Generators / Rectifiers.
Use this second fact to evaluate the tradeoff: Robust capacity makes this the perfect replacement rectifier for a wide variety of high-output battery chargers, especially those with high “boost” ratings. A third point to compare across alternatives is: Straightforward, compact design makes it an easy retro-fit in almost any charger with a “negative base” rectifier – those chargers with the negative DC lead/clamp assembly connected to the rectifier heat sink plate.
Alternative-selection boundary
Choose an alternative when its stated identifiers, application, package, or specifications better match the requirement; no unverified competitor claim is introduced here.
Complete source-backed product details
Heavy-Duty Compact Negative-Base Rectifier. Designed for use in chargers with continuous-duty output ratings up to 100 Amps, and “Boost” ratings up to 600 Amps. This rectifier is a universal replacement for Century, Solar, and other “negative base” chargers at a fraction of the manufacturer’s replacement part price. Robust capacity makes this the perfect replacement rectifier for a wide variety of high-output battery chargers, especially those with high “boost” ratings.
Source product highlights
- Dual diode assemblies, each with an array of 10 diodes, for a total of 20 diodes. Redundant capacity is designed in – if individual diodes fail, load is shifted to remaining functional diodes
- Straightforward, compact design makes it an easy retro-fit in almost any charger with a “negative base” rectifier – those chargers with the negative DC lead/clamp assembly connected to the rectifier heat sink plate
- Full-wave rectification
- Equipped with center-mounted, insulated mounting bolt – for ease of mounting in retro-fit retro-fit applications with Rectifier Mounting Bracket Kit
