power supply unit

type 2225.4

The intended application of the power supply unit covers:

- link and operation of low-voltage consumers with an operating voltage between 0 and 35 VDC. The power input of

the consumer may not exceed 5 A.

Note! Absolutely read!

- Read this guidance exactly. With damage, which is caused by neglect of the guidance, the warranty claim goes

out. For damages we do not take over adhesion.

1. introduction

this power supply unit is universally applicable with its infinitely variable adjustment possibilities of voltage and

current for school, occupation, hobby etc.. An electronic current limiting protects the power supply unit against

overloading. Output voltage and - current are electronically stabilized and infinitely variable adjustable. Thus the

electronic restraint current can as adjustable Current limiting to be used, in order to protect consumers against a too

high power input. In the case of an overloading the output voltage is then lowered accordingly (in the case of short-

circuit on close 0V). With removal of the overload the output voltage adjusted before resets itself automatically. The

respective operating point - voltage - (u) - or restraint current (i) - is displayed by one red LED each. The adjusted

values are readable over 2 LCD displays or analog displays each. The voltage or current adjustment is made by one

double button each (rough- fine). Additionally a change .

. Safety notes 2,1 the power supply unit is in safety class system I as well as in accordance with VDE 0411 and VDE 0805 (EN60950) structured. The supply transformer is structured and with 3,75 kVeff is primarysecondarily checked according to DIN VDE 0551 as safety insulating transformer. It is radio-screened in accordance with VDE 0875T11 curve B. Es is equipped with a VDE checked main with protective grounding and may therefore only to 230-V- with protective grounding be operated or attached.
