Industrial DC UPS Systems and 12/24 VDC Power Supplies
Power supplies and backup power for PLCs, HMIs, industrial computers and communication devices. Choose according to whether you need to bridge a power outage, power equipment from the mains or convert DC voltage.
Choosing UPS systems, power supplies and DC/DC converters
Stable power and protection for production systems
A power failure or voltage drop can stop a machine, damage work in progress, cause data loss or shut down an industrial computer incorrectly. Correctly selected power and backup solutions help prevent these problems.
Bridge short power failures, allow data to be saved safely, shut down an industrial computer correctly or keep equipment running.
View industrial UPS systemsSwitch-mode and industrial power supplies convert 230 VAC mains voltage into a stable 12 or 24 VDC output.
View power suppliesConvert and stabilise DC voltage, for example from a 9–36 VDC input range to 5, 12 or 24 VDC.
View DC/DC convertersSupercapacitor or LiFePO₄ battery?
Suitable for bridging short outages, saving data safely and shutting the system down correctly. Supercapacitors withstand a very high number of charge cycles and do not require regular battery replacement.
Provides a longer backup time and is suitable for applications that must continue operating during a longer outage. The battery offers greater energy capacity, but its service life depends on the number of cycles, temperature and operating conditions.
| Property | Supercapacitor | LiFePO₄ battery |
|---|---|---|
| Typical backup time | Seconds to several minutes | Minutes to tens of minutes |
| Number of charge cycles | Very high | Lower than a supercapacitor |
| Maintenance | Minimal | Battery condition checks |
| Resistance to frequent outages | Very suitable | Suitable |
| Typical use | Saving data and shutting down an IPC correctly | Longer operation of PLCs, IPCs and other devices |
Where are industrial UPS systems used?
Safe data storage and correct operating-system shutdown during a power failure.
Keeping control systems running or safely completing the current production operation.
Backup for industrial switches, routers, gateways and production data collection devices.
Protection of instruments, measuring systems and stored process values.
How to select the right UPS
- Determine the operating voltage: 12 or 24 VDC.
- Add up the current consumption of all backed-up devices.
- Define the required backup time.
- Consider the frequency and duration of power failures.
- Check the available DIN-rail mounting space.
- Check the required communication interfaces.
- Consider management via USB, RS485 or Modbus.
- Verify the operating temperature and cabinet conditions.
For saving data safely and shutting down a computer correctly, a supercapacitor UPS is usually sufficient. For longer operation of a PLC, industrial computer or communication devices during an outage, a UPS with a LiFePO₄ battery is more suitable.

Bicker Review: Jarda Blažek compared 2 smart UPS units with a supercapacitor and a battery
Smart industrial backup power supplies from Bicker protect your production systems and industrial PCs against unexpected power outages, voltage drops, and fluctuations. Jarda Blažek (blaja.cz) investigated the practical differences between UPS units with an integrated supercapacitor and those with a LiFePO4 battery.
New: Bicker DC UPS — Keeping Your Production Technology and Data Safe
Power outages mean downtime, scrap, and data loss. That’s why we’re bringing a new line to the Czech market and to our online shop—products from the German manufacturer Bicker Elektronik. Their DC UPS units maintain 24 V (or 12 V), safely save data, and—where possible—restart devices. Bicker products come with a 3-year warranty. The devices also offer smart functions for system optimization and safety.
