Schauer JAC4024 - 24V, 40A Intelligent Electronic Charger with Float/Maintenance Mode

The Schauer JAC4024 is a Fully Automatic, 3-Stage Electronic Charger with a gray SB50 connector on the 96" DC Lead. Multiple DC Adapters are available to fit various applications. This Intelligent Charger may be left connected to the battery indefinitely, keeping it safely charged without danger of overcharging.

The JAC4024 will charge any type lead acid battery, including conventional flooded cell, maintenance free, deep cycle, gelled-electrolyte, or AGM valve regulated batteries. The 3-Stage Charge Control provides Modified Constant Current Charge to a constant finishing voltage, then to a float/standby voltage to maintain the battery in a fully charged condition.

The JAC4024 features a heavy-duty aluminum case with mounting flanges, and is suitable for on-board mounting in various industrial equipment. The charger automatically detects AC input voltage and operates on either 115V or 230V without user intervention. Supplied with a 72" grounded North America AC input cord equipped with IEC C13 plug for connection at the charger. For international use, simply replace with an AC cord equipped with a locality-appropriate mains power plug and IEC C13 connector.

ORDERING NOTES:

This charger is equipped with a gray SB-50 connector on the DC Lead. Purchase options include your choice of a 12" Industrial Adapter lead that mates to the SB-50 plug. Select your connector plug from the choices on the right and note the product picture for your choice before adding the charger to your cart.

 

Note that there are options for the SB50 connector ONLY (no adapter included). There is also an adapter with stripped wire leads, allowing you to attach your own connector, or make a permanent connection, while allowing the flexibility of disconnection at the SB50.

NOTE: PLP Battery Supply recommends that chargers in this range have an amperage output that equates to a minimum of approximately 10-15% the AH capacity of the battery being charged. For example, this 40 amp charger would be appropriate for a battery with a maximum AH capacity in the 400AH-600AH range. Chargers with marginally low output ratings may result in unacceptably long battery charge times and/or damage to the charger.

Wonderful for dry feet
Material Type: Black - 3 Pairs, Size: X-Large
I have been dealing with dry skin and problems with the heel of my foot, so I thought I would give these a try. I am so glad I did. They moisturize beautifully. A must is you are having trouble with your feet.

X-Large is about a size 12-13 shoe size foot USA.
Material Type: Black - 3 Pairs, Size: X-Large
I love them they work fantastic. I am a big guy with swollen feet. Wear size 12 to 13 USA Shoes. They fit me just fine not tight. My feet felt good after wearing them for two days. Some dry skin pulled off with them and it says to wash by hand. I dont know about the durability but I am hoping to get about 5 uses per pair. Before they become unusable.

Comfortable
Material Type: Black - 2 Pairs, Size: X-Large, Material Type: Black - 2 Pairs, Size: X-Large
I have very sensitive skin, so I usually need to wear socks at all times. These are especially comfortable because they don’t cover the toes, which helps with temperature control. The material is well-balanced—not too thick or too thin—and has just the right amount of stretch. I also appreciate the large traction area, which adds stability. Another plus is that they are completely fragrance-free.
