The Von Duprin 010058 is the OEM 24 VAC to 24 VDC Rectifier Kit for electric strike parts in the Von Duprin 6100 Series, documented in the Von Duprin 6100 Series Data Sheet (doc 105282) and the Von Duprin Electrical Security Products and Accessories Catalog (doc 109981). The catalog ordering designation is SO-24. Per the official Von Duprin documentation: "For AC operation, Von Duprin SO12 (12VAC) or SO24 (24VAC) kit is recommended." The 010058 is the rectifier for 24VAC power sources. No finish options. Available (3-4 weeks).

Why the 010058 Is the Most Common Rectifier Scenario in 6100 Series Installations

The Von Duprin 6100 Series electric strike ships standard as 24VDC fail secure. Every standard 6111, 6112, 6113, and 6121 off-the-shelf configuration is built around 24VDC. This means any installation where a 24VAC power source must drive a standard 6100 Series strike requires the 010058 rectifier - no additional strike re-specification is needed. The installer brings the 010058, connects it between the 24VAC power feed and the strike plug connectors, and the standard 24VDC strike operates correctly from the AC source.

This is the exact reason the 010058 is the more frequently specified of the two Von Duprin rectifier kits. The 010057 (SO-12) is only relevant when both the power source is 12VAC and the strike is also configured for 12VDC - a less common pairing. The 010058 (SO-24) bridges the gap between the most prevalent commercial AC voltage (24VAC) and the most common 6100 Series strike configuration (24VDC).

Why 24 VAC Is Prevalent in Commercial Door Hardware Installations

The 24VAC standard took hold in commercial building systems long before access control migrated to DC-based architectures. Fire alarm panels, intercoms, HVAC controls, and security systems throughout the 1970s, 1980s, and 1990s were built around 24VAC as the universal low-voltage building control standard. Many of these systems remain active and continue to power door release functions at 24VAC.

In retrofit applications - where a 6100 Series strike replaces an older electric strike on an existing 24VAC-powered door - the installer faces a choice: replace the power supply to provide 24VDC, or add the 010058 rectifier kit at the strike and keep the existing 24VAC infrastructure in place. The 010058 is almost always the more cost-effective path. The existing wiring, transformer, and access control circuit remain untouched. Only the small rectifier kit is added at the strike connection point.

Von Duprin 010058: Technical Context in the 6100 Series Option List

The 6100 Series option list per the Von Duprin Electrical Security Products Catalog includes four accessories that are ordered and installed separately: the rectifier kit (SO-12 or SO-24), dual monitor switches, entry buzzer, and Allegion Connect wire extension. The 010058 is one of these four available add-on options and is specified at time of order when 24VAC operation is required.

The 24VDC electrical specifications for the 6100 Series strike confirm why DC is the preferred operating mode: resistance of 72 ohms at 70 degrees Fahrenheit, 0.33 amps seated, and 8 watts. At these levels, sustained DC energization in fail safe configurations produces minimal heat buildup. AC operation at the same voltage generates higher peak currents due to the sinusoidal waveform, increasing heat in the solenoid coil. The 010058 rectifier eliminates this disadvantage by converting the 24VAC supply to clean 24VDC before it reaches the solenoid.

The 6100 Series plug connectors (two-piece, factory furnished) make installing the 010058 straightforward. The rectifier kit connects in-line between the incoming power feed and the existing plug connector, with no modification to the strike body or frame mounting required.
