PRODUCT DESCRIPTION
The Dimension CP-Series are cost optimized power supplies
without compromising quality, reliability and performance. The
most outstanding features of CP20.481 are the high efficiency,
electronic inrush current limitation, active PFC, wide operational
temperature range. The small size is achieved by a synchronous
rectification, LLC technology and by many further technological
design details.
Products of the CP series come with essential functions. The
CP20.481 has a power reserve of 20% included, which may even
be used continuously at temperatures up to +45°C. Additionally,
the device can deliver about 3 times the nominal output current
for 12ms 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 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.
2. INSTALLATION INSTRUCTIONS
WARNING
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. Above 2000m
the overvoltage category is reduced to level II.
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 this document for use above 2000m (6560ft).
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.

6. OUTPUT
The output provides a SELV/PELV 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 > 0.25F 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.

F “Parallel Use” “Single Use” link
Link the two terminal poles when power supplies are connected in parallel to increase the
output power. In order to achieve a sharing of the load current between the individual
power supplies, the “parallel use” regulates the output voltage in such a manner that the
voltage at no load is approx. 4% higher than at nominal load. See also chapter 23.5.

13.LIFETIME EXPECTANCY
The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the
capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years
(131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.

14.MTBF
MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a
device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that
statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it cannot be determined if the failed unit
has been running for 50 000h or only for 100h.
For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.

18.DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground.
The output is insulated to the input by a double or reinforced insulation.
Type and routine tests are conducted by the manufacturer. Field tests may be conducted in the field using the appropriate test
equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output
poles before conducting the test. When testing, set the cut-off current settings to the value in the table below.
We recommend that either the + pole or the –pole shall be connected to the protective earth system. This helps to avoid situations in
which a load starts unexpectedly or cannot be switched off when unnoticed earth faults occur.
