Multiquip 4514 Capacitor Electrolytic 4700UF 450VDC

The Multiquip 4514 is a genuine OEM Capacitor Electrolytic 4700UF 450VDC designed for PRX hybrid power floats, STX55, HTN, HHN, and JWN series ride-on power trowels, as well as WRS ride-on roller screeds. As a direct Multiquip OEM replacement, part 4514 is manufactured to the original electrical specification, ensuring correct capacitance and voltage rating for the control systems it supports. This capacitor is compatible across a broad range of Multiquip and Whiteman ride-on finishing and screed equipment, including STX55Y6, STX55J6, HHN34TVD, HHN31V, HTN28K, HTN27K, and JWN24HTCSL models. Sourcing the correct OEM component matters on high-voltage DC circuits — an undersized or mismatched capacitor can cause control board instability or premature failure.

Key Features

• Correct Capacitance and Voltage Rating — Rated at 4700UF and 450VDC to match the original electrical specification, ensuring stable charge storage and discharge behavior in the control circuit.
• Genuine OEM Component — Supplied directly under Multiquip part number 4514, built to the same standard as the original production unit for consistent electrical performance.
• Drop-In Replacement — Matched to the original mounting footprint and terminal configuration, allowing straightforward installation without circuit modification.
• Broad Fitment Across Finishing Equipment — Fits PRX hybrid power floats, STX55, HTN, HHN, JWN, and JTO series trowels, plus WRSPUDF, WRS5200, and WRS5200DFPU roller screeds.
• Protects Control System Integrity — A capacitor operating within its rated spec smooths voltage fluctuations in the power electronics; a degraded unit can cause erratic blade control, drive faults, or board damage.

An electrolytic capacitor stores and releases electrical energy within a machine's power electronics or motor control circuit. In ride-on trowels and roller screeds, high-capacitance, high-voltage capacitors like this 4700UF 450VDC unit buffer the DC bus voltage, absorbing transient spikes and delivering stable power to drive and blade control systems. When a capacitor degrades — through heat cycling, age, or overvoltage — it loses capacitance, begins to leak current, or fails entirely, which can manifest as intermittent control faults, unexpected shutdowns, or damage to surrounding circuit board components. Replacing a failing capacitor with the correct OEM-rated component restores proper voltage regulation and protects the broader control system.
