Description
Industrial ACT(Advanced Charging Technologies) Quantum battery charger is a gray and black metal unit designed for 480 VAC input.
It has a 4 kW power rating with a maximum output of 50 VDC and 100 A.
This charger is compatible with flooded lead acid, AGM, gel, and Li-Ion battery types.
The front panel includes a digital display screen and a power button.
There are 2 model numbers on this unit.
One is Model Q4-24/36-100-480, The other model number is Q4-C36-XB
I believe it is set up to charge 36 Volt forklift batteries. I am no expert.
Do your homework if interested. See below photos for the information I found using AI search based on the model numbers.

Act quantum model number specs Q4-24/36-100-4
Q4-24/36-100-480) is an industrial smart high-frequency battery charger made by Advanced Charging Technologies (ACT).- Brand / Series: ACT Quantum Q4 Series
- Model Number:
Q4-24/36-100-480 - Nominal Battery Voltage: 24V / 36V max (Supports multi-voltage battery setups)
- Output Current: 100 Amps DC
- Output Voltage: 50 VDC max
- Power Output: 4 kW / 4,000 Watts
- AC Input Voltage: 480 VAC, 3-Phase (3-wire & ground), 50/60 Hz
- Compatible Battery Types: Flooded Lead-Acid, AGM, Gel, and Lithium-Ion (Li-Ion)
- Connectivity: Built-in Wi-Fi and cloud data integration for real-time tracking, management, and peak shaving.
Q4-C36-XB does not refer to a standalone charger model, but rather specifies an internal or external structural component for an ACT Quantum Q4 Charger.- Q4: Quantum Q4 Series Cabinets. This indicates the component is specifically designed to fit or support the 4 kW small-chassis footprint (which typically holds up to two 2kW power modules).
- C36: 36-Volt Configuration. This denotes that the underlying wiring, breakers, or mounting setup is configured specifically to support industrial 36V battery charging applications.
- XB: Internal Blank / Bracket / Expansion Configuration. This typically stands for a structural “Blank” plate, a internal mounting “Bracket”, or an “Expansion Box” option used to cover an empty power module slot or manage cabling within the Q4 chassis.
-
Common Associated ComponentsBecause the Q4 utilizes a modular design, you will usually see this part number on a manifest alongside:
- Power Modules: Such as the 24/36V 480V 3-Phase module slots.
- Blanking Plates: Used to block off the second module bay when the charger is only running a single 2kW module (e.g., operating as a 50A charger instead of a 100A charger).
