Product Description

This unit is a direct‑connect, fully automatic 24‑volt charger and power supply for charging military and aviation batteries without separate charge cables. It delivers controlled DC output for bringing batteries from zero to full capacity and for maintaining them on standby without using trickle charging. The design supports reliable charging and power delivery for aircraft electrical systems where a dedicated 24‑volt source is required.

0 1. Overview

The Activator 282 operates from a wide‑range 90 to 260 VAC input and provides 8‑amp pulses with a 2.5‑amp charge rate on the DC side. A microprocessor‑controlled, multistep charge algorithm manages the charging sequence, including a conditioning mode that top‑charges nickel‑cadmium batteries and rejuvenates lead‑acid batteries. Short‑cell and over‑temperature protection and non‑responsive battery indication are integrated into the control logic.

During operation, 8‑amp pulse output is used to bring deeply discharged batteries up from zero volts, after which the charger transitions through its programmed stages. The unit functions as a standby maintenance device that charges only when required, avoiding gassing, heat buildup, or other effects associated with trickle or float charging.

A digital voltmeter on the front panel continuously displays battery voltage during both charging and standby operation. The unit housing measures 5.5 inches high by 4.5 inches wide by 3.5 inches deep and has a weight of 1.5 pounds. Each charger is supplied with a padded carrying case, a technical manual, and an IEC line cord.
