GENERAL DESCRIPTION
The Dimension CP-Series are cost optimized power
supplies without compromising quality, reliability and
performance. The most outstanding features of the
CP10.241–R1/-R2/-R3 units are the high efficiency,
electronic inrush current limitation, active PFC, wide
operational temperature range and the extraordinary
small size. The units include a decoupling MOSFET for
building 1+1 or n+1 redundant power supply systems.
These redundancy power supplies come with three
connection terminal options; screw terminals, springclamp terminals or plug connector terminals which
allows replacement on an active application.
CP10.242-R2 version feature an enhanced DC input
voltage range.
With high immunity to transients and power surges, low
electromagnetic emission, a DC-OK signal contact for
remote monitoring, and a large international approval
package, makes this unit suitable for nearly every
application.

1. INTENDED USE
This device is designed for installation in an enclosure and is intended for the general professional use such as in
industrial control, office, communication, and instrumentation equipment.
Do not use this power supply in equipment, where malfunction may cause severe personal injury or threaten human
life.
2. INSTALLATION REQUIREMENTS
WARNING
- Do not use the power supply without proper grounding (Protective Earth). Use the terminal on the input block for
earth connection and not one of the screws on the housing.
- Turn power off before working on the device. Protect against inadvertent re-powering.
- Make sure that the wiring is correct by following all local and national codes.
- Do not modify or repair the unit.
- Do not open the unit as high voltages are present inside.
- Use caution to prevent any foreign objects from entering the housing.
- Do not use in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.
Obey the following installation requirements:
- This device may only be installed and put into operation by qualified personnel.
- Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
- The device is designed for use in pollution degree 2 areas in controlled environments.
- The enclosure of the device provides a degree of protection of IP20 according to IEC 60529.
- Mount the unit on a DIN-rail so that the input terminals are located on the bottom of the unit. For other mounting
orientations see de-rating requirements in this document.
- The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do
not cover ventilation grid (e.g. cable conduits) by more than 15%!
- Keep the following installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right sides are
recommended when the device is loaded permanently with more than 50% of the rated power. Increase this
clearance to 15mm in case the adjacent device is a heat source (Example: another power supply).
- Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are
designed for a minimum operating temperature of 60°C for ambient temperatures up to +45°C, 75°C for ambient
temperatures up to +60°C and 90°C for ambient temperatures up to +70°C. Ensure that all strands of a stranded wire
enter the terminal connection. Check also local codes and local requirements. In some countries local regulations
might apply.
- This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect. If
damage or malfunction should occur during installation or operation, immediately turn power off and send the
device to the factory for inspection.
- The device is designed, tested and approved for branch circuits up to up to 30A (UL) or 32A (IEC) without additional
protection device. If an external fuse is utilized, do not use circuit breakers smaller than 10A B- or C-Characteristic to
avoid a nuisance tripping of the circuit breaker.
- A disconnecting means shall be provided for the input of the power supply.

6. OUTPUT
The output provides a SELV/PELV/ES1 rated voltage, which is galvanically isolated from the input voltage. The output
of the devices includes a decoupling MOSFET for building 1+1 or n+1 redundant power supply systems.
The device is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large
capacitors, such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance larger than 1.5F are
connected to the output, the unit might charge the capacitor in the Hiccup
The device is featured with a “soft output regulation characteristic” in order to achieve current share between
multiple devices when they are connected in parallel. The “soft output regulation characteristic” regulates the output
voltage in such a manner that the voltage at no load is approx. 4% higher than at nominal load.

Back-feeding loads
1) This current is also available for temperatures up to +70°C with a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
2) The fuse braking current is an enhanced transient current which helps to start heavy loads or to trip fuses on faulty output branches. The
output voltage stays above 20V. See chapter 24.1 for additional measurements.
3) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s. After this, the
output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload
exists. If the overload has been cleared, the device will operate normally. See Fig. 6-2.
