The following technical explanations provide useful informa-tion on important technical terms used in this catalog.Depending on the proposed use, additional or differentdefinitions may be required. The following explanations aretherefore not exhaustive.

Duty ratio, DRThe duty ratio (DR) of a transformer is the ratio betweenload time and cycle duration. Unless specified otherwise,the cycle duration is 10 min.

The reduction factor, f, indicates the possible reduction ofthe size in comparison with continual service.

Short time operation

If the design rating for continuous operation is smaller thanthe rated output, the transformer can be overloaded forshort periods provided it does not heat to more than thepermitted overtemperature.

Insulation classes

The provisions of IEC 85 and IEC 216 describe the heatresistance if insulation classes.

Normally, we design transformers according to class B alt-hough most materials can resist much higher temperatures(e.g., copper wire and impregnating resin are at least classF resistant).

Insulation structure

The following structures are possible:

-Transformers with basic insulation (e.g., power transformers for general service, control transformers)

-Transformers with double or extra strong insulation (e.g.,safety isolating or isolating transformers)

-Transformers without insulation between input and output (so called autotransformers)

Short-circuit resistance

The following distinctions are made:

Unconditionally short-circuit resistant transfor-mersare dimensioned in such a way that the temperature underoverload or short circuit conditions does not exceed thepermitted limits. To ensure this, the size must at least be dou-ble, and the no-load voltage is significantly higher than therated voltage.

Conditionally short-circuit resistant transformershave a built-in protection mechanism which opens the inputor output circuit when the transformer is overloaded orshort-circuited (e. g., fuses, thermal links, PTC thermistor,thermal switch).

Transformers without short-circuit resistance must be protected against overload or short circuit by amechanism that is not integrated in the transformer. This pro-tection must be provided by the user.

Protection types

The protection type marking consists of a code of two con-stant letters, viz. "IP" and two digits, e.g., IP 23.






First digit Protection

Description Explanation

0 No protection No protection availible

1Protection againstdrops of water fal-ling vertically

Drops of water falling vertically shall have noharmful effect..

3Protection againstspray water

Water falling from any angle less than 60degrees from vertical shall have no harmfuleffect.

4Protection againstsplash water

Water splashing from any direction shall haveno harmful effect.

5

Protection againstwater jets

A jet of water from a nozzle directed at thetransformer from any direction shall have noharmful effect.

6Protection againstflooding

No harmful amount of water to which thetransformer is exposed during a temporaryflooding must enter.

7

Protection againstimmersion

If the transformer is immersed in water underspecified pressure and time, no harmfulamounts of water must enter the transformer

Protection classThe protection class is a design feature of a product whichdesignates safety against shock current.

Protection class I: Product with safety ground terminal and basic insulation

Protection class II: Product without safety ground terminal and double or extra strong insulation.

Ambient temperatureIf no non-standard ambient conditions are specified in theorder, the transformer is designed for ta=40°C. If the actualtemperature is higher, the rated output must be reduced asshown in the following figure.

Laws and regulationsUnless required otherwise, we make our transformers toreflect state-of-the art and comply with the following lawsand regulations:

II..

I. GeneralBy placing the order, the buyer accepts these "General Terms of Business" asexcusive basis for transaction of business. Buyer's terms, if any, are herebyexpressly excluded and do not apply even in absence of our express objection.Any other agreements are only valid if made in writing.

II. II. Prices

Our prices are without obligation and quoted ex works without packaging andin EURO currency, exclusive of value-added tax, which will be charged at therate applicable at the time of delivery. Copper prices of 150.00 EUR or morefor each 100 kg lead to price adjustment prorated the specified weight.

III. III. Terms of payment/setting off

1. Payment due to us is defined in calendar terms (§ 286 cl. 2 no. 1 BGB -German Civil Code) and mature 30 days after invoice date.

2. All payments must be made free supplier's point of payment; discount at2% can be deducted from all payments made within 10 days of the invoicedate.Deliveries to unknown buyers are only made COD.

3. The buyer can only set off payments which are not in dispute or are the sub-ject of a final court judgment.

IV. Contract conclusion /deliveries

1. Orders to agents, any collateral agreement, amendments and modificationsare only binding on us if made in writing.

2. Dimensions, output data and illustrations correspond to the specified pro-ducts; deviations are expressly reserved.

3. All shipments are made ex works at buyer's risk. The risk passes to buyerwhen the consignment in a state ready for use has been shipped or collec-ted. This also applies to all shipments made free, in our own fleet of trucksor if the goods are consigned to buyer's order. Partial shipments which thebuyer can reasonably be expected to accept are permitted.

4. Goods shall be accepted immediately upon completion. If buyer delaysacceptance, we can charge warehousing cost at 0.5% of the invoiceamount for every month, including fractions thereof, subject to a maximumof 5% of the value of the goods.

5. All shipments are made by the agreed date as far as possible. We areresponsible for delays only in cases of intent or gross negligence and ifacting under the constraints of law provided the buyer can submit poof ofthe damage caused. The damage is limited to 5% of the value partial deli-very or delivery which is delayed. Force majeure is cause for a reasonableextension of the delivery period.

V. Liability for defects

We are responsible for defects as defined in §§ 434, 435 BGB as follows:

1. All parts or services which become unusable or whose usability is substanti-ally limited for reasons before the passing of risk, in particular due todefects of type, defective material or poor workmanship, within 60 monthsirrespective of the operating time calculated from the date at which the riskpassed, shall at buyer's option be repaired free, delivered new or madenew.

Any defect must be communicated to us in writing without delay. The termfor electronic devices is 36 months. If buyer's choice (repair or replace-ment) entails unreasonably high cost, we can refer the buyer to a versionwhich is less expensive for us.

2. Buyer must allow us reasonable time and opportunity for repairing a defect.Otherwise we are released from our liability for the defect.

3. Any other claims by buyer on us are excluded unless such claims are sub-stantiated in applicable law.
