PRODUCT DESCRIPTION SHORT-FORM DATA
The Dimension CP-Series are cost optimized power
supp ies without compromising qua ity, re iabi ity and
performance. The CP-Series is part of the DIMENSION
power supp y fami y. The most outstanding features
of CP20.481 are the high efficiency, e ectronic inrush
current imitation, active PFC, wide operationa
temperature range. The sma size is achieved by
a synchronous rectification, LLC techno ogy and by
many further techno ogica design detai s.
The C-Series inc udes a the essentia basic functions.
The device has a power reserve of 20% inc uded,
which may even be used continuous y at temperatures
up to +45°C. Additiona y, the CP20.481 can de iver
about 3 times the nomina output current for 12ms
which he ps to trip fuses on fau ty output branches.
High immunity to transients and power surges as
we as ow e ectromagnetic emission, a DC-OK re ay
contact and a arge internationa approva package
make this unit suitab e for near y every situation.

11. MTBF
MTBF stands for Mean Time Between Fai ure, which is ca cu ated according to statistica device fai ures, and indicates
re iabi ity of a device. It is the statistica representation of the ike ihood of a unit to fai and does not necessari y represent
the ife of a product.
The MTBF figure is a statistica representation of the ike ihood of a device to fai . A MTBF figure of e.g. 1 000 000h means
that statistica y one unit wi fai every 100 hours if 10 000 units are insta ed in the fie d. However, it can not be determined
if the fai ed unit has been running for 50 000h or on y for 100h.
For these types of units the MTTF (Mean Time To Fai ure) va ue is the same va ue as the MTBF va ue.

Instructions for Wirings:
a) Use appropriate copper cab es that are designed for minimum operating temperatures of:
+60°C for ambient up to +45°C and
+75°C for ambient up to +60°C minimum
+90°C for ambient up to +70°C minimum.
b) Fo ow nationa insta ation codes and insta ation regu ations!
c) Ensure that a strands of a stranded wire enter the termina connection!
d) Unused termina compartments shou d be secure y tightened.
e) Ferru es are a owed.
Dais chaining:
Daisy chaining (jumping from one power supp y output to the next) is a owed as ong as the average output current
through one termina pin does not exceed 25A. If the current is higher, use a separate distribution termina b ock as shown
in Fig. 13-2.

attempts to restart.
2) In safety critica situations a temperature sensor, which is insta ed inside the unit on a critica component, turns the unit off (e.g. de-rating
requirements not observed, high ambient temperature, venti ation obstructed or the mounting orientation de-rating is not fo owed). There is no

19. Die ectric Strength
The output vo tage is f oating and has no ohmic connection to the ground.
The output is insu ated to the input by a doub e or reinforced insu ation.
Type and routine tests are conducted by the manufacturer. Fie d tests may be conducted in the fie d using the appropriate
test equipment which app ies the vo tage with a s ow ramp (2s up and 2s down). Connect a input-termina s together as we
as a output po es before conducting the test. When testing, set the cut-off current settings to the va ue in the tab e be ow.
We recommend that either the (+) po e or the (–) po e sha be connected to the protective earth system. This he ps to avoid
situations in which a oad starts unexpected y or can not be switched off when unnoticed earth fau ts occur.
