18. 00 2 4 Main Isolation Transformer T1 Snubbing Network amp Output Rectifier T1 provides the required isolation between input and output and its small size is due to the high operating frequency and low loss ferrite core This transformer is hi pot tested to 3750V to ensure compliance with the most stringent VDE safety regulations The main secondary winding is centre tapped thus requiring only 2 diodes D43 to provide full wave rectification resulting in reduced power loss R11 C15 R79 C66 and C67 provide some high frequency snubbing The effect of this snubbing is twofold firstly it reduces high frequency spikes due to leakage inductance and secondly it shapes the load line resulting in reduced switching losses within Q1 and Q2 2 5 Output Filter amp Minimum Load T5 C68 to C73 C76 and C78 reduce the 166kHz ripple to an acceptable level while C74 C75 L6 C79 C80 and C81 reduce the level of higher frequency noise components Q9 switches in R81 R82 and RLY1 which serve as a minimum load to enhance stability 09 is activated via D41 only when the supply is active This ensures that R81 R82 and RLY1 will not drain any back up batteries that might be present on the supply output while the supply is switched off or the mains supply is interrupted 2 6 Output Voltage Regulation amp Switching Transistor Drive The output voltage is sampled via R84 and R83 or SKT 7 if remote sense is used fed to IC8 a programmable

29. 6 Caution Earthing Of Rack Frame The power supply case is internally connected to mains earth Because the unit s case and the rack frame in which it is usually installed are painted a secure electrical earth ing connection between the unit and the rack is not guaranteed i e it is reliant on breaking through the paint coating Itis therefore strongly advised that an additional and secure electrical connection is pro vided by means of the supplied earth lead refer to Section 7 2 Failure to do so may result in harmful voltage potentials between the power supply and rack frame and or miscellaneous power supply switching noise problems in both receivers and transmit ters Note Failure to comply with the above instruction may result in the power supply falling short of the emissions requirements of ETS 300 279 3 1 7 Caution Cabinet Requirements To Meet Safety Specifications In order to meet stringent safety obligations it is imperative that the power supply is mounted in a cabinet which meets the requirements of IEC950 Specifically the top and sides of the cabinet must comply with one of the following holes must not exceed 5mm in any dimension or holes must not exceed 1mm in width regardless of length or side panels must be provided with louvres that are shaped to deflect outwards an external vertically falling object or tops must be so constructed that direct vertical entry of a falling object is prevented from reaching b
30. 7 4 Noise Interference Suppression Earthing 7 4 1 Introduction The problem of noise interference may occur in installations which include T300 series receivers and T807 808 power supplies The procedures outlined in the following Sec tions will minimise the possibility of noise interference from three main sources noise directly picked up via the aerial system if the receive aerial is within approx imately 3 metres of the power supply noise directly radiated into the receiver noise carried via the 13 8V line to the receiver These procedures should also be followed to ensure that both the individual units and the rack frame are earthed to mains earth for reasons of mains safety 7 4 2 Mounting The 1807 808 should be mounted as far as possible from the receiver i e in a typical repeater system there should be a transmitter duplexer and speaker panel between the power supply and the receiver Mount the aerial at least 3m from the T807 808 7 4 3 Earthing Ensure that all the individual units receiver transmitter power supply are earthed to the front of the rack via the front panel and the rear of the rack frame via a separate earthing strap T807 808 power supplies already have the front panel earthed to the chassis On other units a small amount of paint may need to be removed from the back of the front panel 31 08 96 Copyright TEL M800 00 T807 808 Installation B7 5 around the button head screws to ensure a go

A Check the fuse If it is blown check that the correct rating and type was fitted and fit a new fuse of the correct rating Note If the fuse was of a lower rating and there are no signs of component dam age it may be worthwhile fitting a new fuse replacing the covers and switching the supply on If the new fuse blows proceed with fault finding as described in the following sections 6 2 Component Checks 6 2 1 General If a transistor is suspected of faulty operation an indication of its performance can be assessed by measuring the forward and reverse resistance of the junctions First make sure that the transistor is not shunted by some circuit resistance unless the device is completely desoldered A 20k ohm V or better multimeter should be used for taking the measurements using only the medium or low resistance ranges The collector current drawn by multijunction transistors is a further guide to their per formance If an IC is suspect the most reliable check is to measure the DC operating voltages Due to the catastrophic nature of most IC failures the pin voltages will usually be markedly different from the recommended values in the presence of a fault The recommended values can be obtained from either the circuit diagram or the component data catalogue Copyright TEL 31 08 96 B6 4 T807 808 Fault Finding M800 00 6 2 2 Initial Checks Some components are more likely to be at fault than others and it is recomme
