Choosing among industrial power supplies transformers comes down to a basic split: do you need power for access-control hardware, or a pulse-width speed-control unit? The K80 and Altronix entries target access-control roles at notably different output levels, while the two HJ-22280T entries are speed-control choices. Start with the electrical role, then use condition and listed price to narrow the field.
Quick take
- Access-control hardware with the K80 format: The Access Control Power Supply K80 Switch is aimed at electric locks, access controllers, exit buttons, and RFID card readers.
- A dedicated access-control controller setup: Altronix AL1024ULACMCB is the choice to focus on when an access-control power controller format is central to the installation.
- Pulse-width speed control: Both HJ-22280T entries belong in the speed-control side of the decision rather than the access-control side.
- Condition distinction: The K80 and both HJ-22280T entries are listed as New, while the Altronix is listed as New - Open box.
Listed-price comparison
| Listed option | Listed price | Price bar | Primary role |
|---|---|---|---|
| Access Control Power Supply K80 Switch DC 12V 3A AC 110~260V for grey | USD 22.57 | Access control | |
| Altronix AL1024ULACMCB Access Control Power Supply Controller 24VDC 10A | USD 140.45 | Access-control controller | |
| Pulse width speed control power supply DC HJ-22280T speed control power supply | USD 184.77 | Speed control | |
| Speed control power supply DC HJ-22280T Pulse width speed control power supply | USD 199.99 | Speed control |
Decision matrix
- Choose the K80 when the required output is DC 12V/3A and the input range needs to accommodate AC 110~260V at 50~60Hz. Its description also identifies NC/NO outputs and automatic short-circuit protection.
- Choose the Altronix AL1024ULACMCB when the application calls for a stated 24VDC, 10A supply plus an integrated ACM8CB eight-output PTC power-limited access power controller module.
- Keep the two HJ-22280T entries in consideration only for the speed-control role indicated by their titles. The Topped entry carries explicit Model HJ-22280T and MPN HJ-22280T identifiers.
- If condition is a deciding factor, the Altronix entry is the only one marked New - Open box; the other three are marked New.
Product notes
Access Control Power Supply K80 Switch DC 12V 3A AC 110~260V for grey
The K80 is the direct pick for an access-control task built around the listed DC 12V/3A output. Its description specifically names electric locks, lock controllers, RFID card readers, password keyboards, and exit buttons, making its intended role unusually clear among the four choices. The wide stated AC 110~260V input range is another concrete fit point, and the grey color is specified. At USD 22.57, it is the lowest-priced entry in the comparison. Its limitation is output format: the K80 is not the 24VDC, 10A access-control controller configuration named for the Altronix unit.
Altronix AL1024ULACMCB Access Control Power Supply Controller 24VDC 10A
Altronix AL1024ULACMCB suits an access-control installation that calls for the listed 24VDC 10A supply and a controller with eight outputs. The description identifies an AL1024ULXB2 main power supply board and integrated ACM8CB module, while also naming magnetic locks, electric strikes, card readers, and other access-control hardware as applications. At USD 140.45, it sits between the basic K80 access-control supply and the two speed-control entries. The trade-off is its stated New - Open box condition, whereas the K80 and both HJ-22280T choices are marked New.
Pulse width speed control power supply DC HJ-22280T speed control power supply
Choose the Pulse width speed control power supply DC HJ-22280T when the goal is a New pulse-width speed-control entry carrying the HJ-22280T name in its title. It is separate in purpose from the access-control supplies, so it makes sense for a speed-control requirement rather than an electric-lock or reader-power role. The listed price is USD 184.77, positioning it toward the upper end of this four-option group. That price is the main limitation when the application can instead use the lower-priced K80 access-control supply; the two entries address different roles and should not be treated as interchangeable.
Speed control power supply DC HJ-22280T Pulse width speed control power supply
The Speed control power supply DC HJ-22280T stands out for shoppers who want the model identifier stated directly: both Model and MPN are listed as HJ-22280T, and the type is listed as Speed control power. Its title also explicitly calls out pulse-width speed control, keeping the intended role aligned with the other HJ-22280T entry rather than either access-control choice. The entry is marked New and has a listed price of USD 199.99. The limiting factor is that it is the highest-priced option here, so the explicit model and MPN identification need to matter to the intended selection.
Final recommendation by use case
- Pick the K80 for the described electric-lock, RFID reader, exit-button, and access-controller role.
- Pick the Altronix AL1024ULACMCB for an access-control controller arrangement rather than a basic K80-style supply.
- Pick the Pulse width speed control power supply DC HJ-22280T when a New HJ-22280T speed-control entry best fits the job.
- Pick the Speed control power supply DC HJ-22280T when the stated HJ-22280T model and MPN identifiers are the deciding details.
