RODUCT DESCRIPTION

The Dimension CP-Series are cost optimized power supplies without compromising quality, reliability and performance. The most outstanding features of the CP20 series are the high efficiency, electronic inrush current limitation, active PFC, wide operational temperature range and the extraordinary small size.

The CP20.241-C1 is equipped with conformal coated pcboards preferred for applications in harsh areas.

The CP20.241-S1 is equipped with quick-connect springclamp terminals preferred for applications which are exposed to mechanical vibration. The CP20.241-S2 has push-in terminals optimized for easy cabinet wiring.

The CP20.241-V1 is equipped with a remote ON/OFF feature and the CP20.242 features an enhanced DC input voltage range.

The devices have a power reserve of 20% included, which may even be used continuously up to +45°C.

High immunity to transients and power surges as well as low electromagnetic emission, a DC-OK relay contact and a large international approval package makes this unit suitable for nearly every situation.

NTENDED USE

This device is designed for installation in an enclosure and is intended for commercial use, such as in industrial control, process control, monitoring and measurement equipment or the like.

Do not use this device in equipment where malfunction may cause severe personal injury or threaten human life.

NSTALLATION INSTRUCTIONS

Risk of electrical shock, fire, personal injury or death

- Turn power off before working on the device. Protect against inadvertent re-powering.

- 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 instructions: 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. Install the device in an enclosure providing protection against electrical, mechanical and fire hazards. Install the device onto a DIN-rail according to EN 60715 with the input terminals on the bottom of the device. Other

mounting orientations require a reduction in output current. 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.

Unused screw terminals should be securely tightened. The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed. The enclosure of the device provides a degree of protection of IP20. The isolation of the device is designed to withstand impulse voltages of overvoltage category III according to IEC

60664-1. The device is designed as “Class of Protection I” equipment according to IEC 61140. Do not use without a proper PE (Protective Earth) connection. Use the terminal on the input block for earth

connection and not one of the screws on the housing. The device is suitable to be supplied from TN-, TT- and IT mains networks. The voltage between the L or N terminal

and the PE terminal must not exceed 300Vac continuously. The input can also be powered from batteries or similar DC sources. The voltage between the input terminal and the

PE terminal must not exceed 375Vdc continuously. A disconnecting means shall be provided for the input of the device. The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not

cover ventilation grid! The device is designed for altitudes up to 6000m (19685ft). See additional requirements in the product datasheet for

use above 2000m (6560ft).

Aug. 2019 / Rev. 1.1 DS-CP20.241-EN - All parameters are typical values specified at 230Vac, 50Hz input voltage, 24V, 20A output load, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.

Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and right side. Increase the 5mm to 15mm in case the adjacent device is a heat source. When the device is permanently loaded with less than 50%, the 5mm can be reduced to zero.

The device is designed, tested and approved for branch circuits up to 32A (IEC) and 30A (UL) 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.

The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the same as the ambient or surrounding air temperature and is defined 2cm below the device.

The device is designed to operate in areas between 5% and 95% relative humidity.

Installation instructions for use in hazardous location areas:

The power supply is suitable for use in Class I Division 2 Groups A, B, C, D locations. See chapter 20 for details.

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.

Wiring must be in accordance with Class I, Division 2 wiring methods of the National Electrical Code, NFPA 70, and in accordance with other local or national codes.

A suitable enclosure must be provided for the end product which has a minimum protection of IP54 and fulfils the requirements of the EN 60079-0.

UTPUT

The output provides a SELV/PELV/ES1 rated voltage, which is galvanically isolated from the input voltage. 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 > 1F are connected to the output, the unit might charge the capacitor in an intermittent mode.

The output is electronically protected against overload, no-load and short-circuits. In case of a protection event, audible noise may occur.

2) 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.

The hold-up time is the time during which a power supply’s output voltage remains within specification following the loss of input power. The hold-up time is output load dependent. At no load, the hold-up time can be up to several seconds. The green DC-ok lamp is also on during this time.

ELAY CONTACT

This feature monitors the output voltage on the output terminals of a running power supply.

As soon as the output voltage reaches typ. 90% of the adjusted output voltage level. As soon as the output voltage dips more than 10% below the adjusted output voltage.

Short dips will be extended to a signal length of 100ms. Dips shorter than 1ms will be ignored.
