GENERAL DESCRIPTION

The DIMENSION UC-Series are DC-UPSs utilizing

Electrochemical Double Layer Capacitors (EDLC),

commonly known as Ultracapacitors or Supercapacitors,

which are installed inside the DC-UPS. They can bridge

power failures or voltage fluctuations and supply

voltage to the DC 24V bus for a certain period, which

allows for a safe shut-down of the system. Expensive

downtimes, long restart cycles and loss of data can be

avoided.

In times when the power supply provides sufficient

voltages, the DC-UPS stores energy in the capacitors. In

case of a mains voltage fault, this energy is released to

the DC bus in a regulated process.

The DC-UPSs are maintenance-free and have a similar

lifetime expectancy as power supplies. No regular

replacement of the capacitors is necessary as is required

for battery based DC-UPS systems. The wide

temperature range from -40°C to +60°C makes the unit

suitable for many applications.

The DC-UPSs come in two versions which differ in the

size of the installed capacitors.

A current overloading of the DC-UPS cannot happen, independent of which sizes of power supplies are used on the input of the DC-UPS. The current limitation works in a switching mode which reduces the power losses and heat generation to a minimum.

PC-MODE The PC-mode always turns the output off for at least 5s after a buffer event lasting longer than 1s, independent of whether the 24V may have recovered during this time. This function ensures that the PC gets a restart signal. To enable a safe shut-down of the system, the forced turn off of the output is delayed with a constant time of 70s.

The biggest influence in lifetime is a combination of operating voltage and operating temperature of these capacitors. To gain longest lifetimes, PULS does not utilize the full allowed working voltage for these capacitors and therefore accepts a slightly shorter buffer time.

An external protection is only required, if the supplying branch has an ampacity greater than this. If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of the circuit breaker. A minimum value of 20A B- or C-Characteristic breaker should be used.

Recommendations for building redundant power systems: a) b) c) d) e) Use separate input fuses for each power supply. Set the power supply into “Parallel use” mode if available. Use a redundancy module to decouple the two power sources. Monitor the individual sources. Therefore, use the alarm contacts of the YRM2.

The units kJ (kilo Joule) or kWs (kilo Watt seconds) is used for specifying the installed storage capacitor size. 1 kJ = 1 kWs = 1000Ws The stored energy of a capacitor can be calculated with the following formula: Energy (Ws) = C *U 2 2 For example: A 350F (Farad) capacitor which is charged to 2.5V has the following energy E= 2 350F * 2.5V = 1093Ws = 1.

Always start with the most likely and easiest to check condition. Some of the suggestions may require special safety precautions. See notes in section 2 first.
