Intelligent μExtension module for supercap UPS

 The uninterruptible power supply of industrial computers, embedded PCs and gateways with highly durable UPS systems in becoming an increasingly crucial factor both in industrial and medical technology. 

The new PSZ-1063 μExtension module from Bicker Elektronik extends the features of the maintenance-free DC UPS systems UPSIC-1205 / UPSIC-2403 and the DC/DC converter with backup feature DC2412-UPS / DC2412-UPS-LD (Load Dump Version) with numerous functions that ensure optimal connection and protection of current mainboards.

The plug in module is simply attached to the COM interface of the DC UPS in a sandwich process and connected to the RS-232 interface of the mainboard via appropriate accessory interface cables (PSZ-1046 or PSZ-1048). To protect the computer system against voltage fluctuations, flicker, voltage dips or failure of the supply voltage, the mentioned DC UPS systems from Bicker Elektronik are equipped with ultracapacitors (so-called supercaps / supercapacitors) as energy storage, which are characterised by extremely short charging times, a wide temperature range and a high current carrying capacity and power density.

Due to the high cycle stability (more than 500,000 charging cycles), such DC UPS systems have a particularly long service life. For the supplied computer system this means an increase of long term availability while minimising maintenance efforts.

Data monitoring in real time

The continuous operation data acquisition of the new μExtension module PSZ-1063 now allows real time data monitoring. The data is continuously recorded via the I²C interface of the DC UPS system and stored in the μExtension module. The module's RS232 interface allows the data to be forwarded to the host, enabling easy implementation into the computer system. The open communication protocol with extensive list of commands offers system developers individual connection possibilities to their specific system.

Integrated reboot function

Another core feature of the PSZ-1063 module is the built-in reboot feature, which enables the system to automatically reboot as soon as the power supply voltage returns during the shutdown process or at a later point in time. When the input voltage is present, the startup function of the mainboard can be activated directly via BIOS. For example, self-sufficient computer systems can be shut down in a controlled manner after a power failure and then restarted automatically without any operator intervention.

Controlled release of output voltage

Optionally, a safety function of the additional μExtension module PSZ-1063 can be activated for the output or supply release to the system, which ensures that the output of the DC UPS is not enabled until the supercapacitors have reached at least 90% of their capacity. A safe and reliable shutdown process of the system is thus always guaranteed.

Software independent operation

The DC UPS can also be operated without software on the host. The time values for power fail (PF) and shutdown timers can be set directly on the μExtension module PSZ-1063 using a DIP switch block. In this configuration, the add-on module generates the trigger signal for system shutdown via the power button connection of the mainboard. 

Bicker Elektronik offers matching two wire twisted cables for mainboard connection, the PSZ-1043 with ‘open end’ connection and the PSZ-1044 with 2.54mm connection. In addition, the options for software controlled configuration of all parameters using free software ‘UPS Control Centre’ from Bicker Elektronik remain unchanged.

Bicker Elektronik grants a three year warranty on the μExtension module PSZ-1063, as well as a long-term availability of at least five years. In addition, Bicker Elektronik offers comprehensive value added services, especially for system developers. These include personal on site consulting during the design in process by experienced sales engineers and subsequent project support by the sales, development and service teams of Bicker Elektronik. 

As part of the Power+Board program, Bicker Elektronik customers receive tested and perfectly matching bundles consisting of power supply + mainboard + industrial-grade accessories. On request, the specialists from Bicker Elektronik realise customer specific special solutions and also offer extensive laboratory and measuring services for complete customer systems.
