GENERAL DESCRIPTION
The Dimension C-Series are cost optimized power supplies without compromising quality, reliability and performance. The C-Series is part of the DIMENSION power supply family. The most outstanding features of CPS20.241 are the high efficiency, electronic inrush current limitation, active PFC, wide operational temperature range. The small size is achieved by a synchronous rectification and further technological design details.
The C-Series includes all the essential basic functions. The devices have a power reserve of 20% included, which may even be used continuously at temperatures up to +45°C. Additionally, the CPS20.241 can deliver about 4 times the nominal output current for 15ms which helps to trip fuses on faulty output branches.
High immunity to transients and power surges as well as low electromagnetic emission, a DC-OK relay contact and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.

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.
This device is designed for use in hazardous, non-hazardous, ordinary or unclassified locations.
2. INSTALLATION REQUIREMENTS
This device may only be installed and put into operation by qualified personnel. 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 unit to
the factory for inspection. Mount the unit on a DIN-rail so that the terminals are located on the bottom of the unit. For other mounting
orientations see de-rating requirements in this document. See chapter 24.13. This 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 (e.g. another power supply).
A disconnecting means shall be provided for the output of the power supplies when used in applications according to CSA C22.2 No 107.1-01.
WARNING
Risk of electrical shock, fire, personal injury or death.
- 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.
Notes for use in hazardous location areas:
The power supply is suitable for use in Class I Division 2 Groups A, B, C, D locations and for use in Group II Category 3 (Zone 2) environments and are evaluated according to EN 60079-0:2012 and EN 60079-15:2010.
WARNING EXPLOSION HAZARDS!
Substitution of components may impair suitability for this environment. Do not disconnect the unit or operate the voltage adjustment or S/P jumper unless power has been switched off or the area is known to be non-hazardous.
A suitable enclosure must be provided for the end product which has a minimum protection of IP54 and fulfils the requirements of the EN 60079-15:2010.

Do not operate this power supply with DC-input voltage. Use the CPS20.241-D1 unit instead.
5. INPUT INRUSH CURRENT
An active inrush limitation circuit limits the input inrush current after turn-on of the input voltage and after short input voltage interruptions.

PLUS
Mode 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. 6-3
***) Discharge current of output capacitors is not included. ****) This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. It is not
guaranteed value which can be achieved. The typical value is about 28.5V (in “single use” mode).
