Description
Mallory CGS403U040X4C 40000 MFD 40VDC Capacitor Bank Crydom D1210 Relay 3U Rack
This is a pre-wired capacitor bank assembly built on a 3U rack-mount panel, combining two large Mallory CGS403U040X4C electrolytic capacitors, a Crydom D1210 solid state relay, and a transformer — all mounted and wired to a numbered terminal block. The assembly appears to be a custom power filtering or energy storage subassembly, likely from a larger industrial or AV power system.

Applications
Large electrolytic capacitor banks of this type are commonly used in power supply filter stages, motor drive systems, audio amplifier power rails, and industrial energy storage applications where bulk capacitance is needed to smooth DC voltage and absorb transients. The Mallory CGS series are high-capacitance snap-in/bolt-terminal electrolytics built for industrial and professional use. The Crydom D1210 is a 10-amp, 120VAC output solid state relay used for switching AC loads with a DC control signal, a common pairing in relay-controlled power circuits. This custom rack-panel assembly integrates these components for installation in a 19-inch equipment rack, suggesting it originally served as part of a power conditioning, soft-start, or energy storage module within a larger system.
This Mallory CGS403U040X4C 40000 MFD 40VDC capacitor bank assembly has been inspected and appears to be in good used condition. The two Mallory capacitors, Crydom D1210 solid state relay, transformer, and wiring harness are all present and intact on the 3U rack-mount panel. The black panel shows some scuffing and light scratches consistent with normal rack use. Wiring and terminal connections look complete and undamaged in the photos. This assembly has not been powered up or tested at our facility, but was pulled from a working environment where it was previously in use. Please view our photo set and contact us if you have any questions.
