Page 10: Putting Into Operation
This mode of operation is reached, when the LED-indicator 'CV' lights up. Because of the high stability of ATLAS, it is possible to adjust accurately the output voltage to several decades. For this, an adequate digital voltmeter should be used. The local adjustment is performed using the voltage control knob 'VOLTAGE'. -
Page 11: Remote Voltage Programming
Response can thus vary depending on individual parameters. The fastest output voltage response is between 200 and 400ms for a programming step of 100% and depending on the type of power supply. Atlas 2000 Page 11 von 26 ISSUE 07/05... - Page 12 The Instruments are factory-preset for 10V programming. For 5V programming pull the regulation board from the power supply, short the jumper 'J301' (see last page), push the regulation board back on it´s place. Atlas 2000 Page 12 von 26 ISSUE 07/05...

In order to obtain an even load distribution it is recommended, to adjust the 'VOLTAGE' and 'CURRENT' control of both ATLAS in such a way that they display an equal voltage. Devices should be switched on and off simultaneously.
- Page 18 The master can limit only the current through +R load. The current limit from slave can be set with a resistance (< 10KOhms), connected between TB3-3 and TB3-11 (see chapt 3.6.1). Power must be switched on and off simultaneously on both units. Atlas 2000 Page 18 von 26 ISSUE 07/05...

Page 19: Simple Connection Of Load Terminals
3.8.1 Simple output load terminals connection In order to get an even load current distribution, both ATLAS power supplies have to be adjusted to the same output voltage prior to connecting the output load terminals. The connecting cables should be as short as possible and with corresponding cross section. - Page 20 Remove jumper “J304” on the Regulation board (see last page) Fig. 11 Atlas 2000 Page 20 von 26 ISSUE 07/05...

(< 50ppm/°C) and oversized (< 0,5W). It´s value can vary between 0KOhm and 12KOhm. The threshold is proportional to the resistance. For 12KOhm the threshold will be 120% from the nominal output voltage. Atlas 2000 Page 21 von 26 ISSUE 07/05... - Page 22 Opt.34- board (Interface-card) too, if the Opt.34-board is activated. If the programming voltage can not sink current, a 100 Ohm/0,5W resistor should be connected parallel to the source. Atlas 2000 Page 22 von 26 ISSUE 07/05...
- Page 23 3.9.3 Delayed current limiting. The load can draw from the power supplies ATLAS an overcurrent (150% from the actual current limit, I ) for a period not exceeding 500ms. After the delay-time, the current will be limited to the currrent limit. Every overcurrent period is followed by a relaxtion-time, approx.

(Opt.34) For a complete description of the interface-card, consult the manual. There only aspects typical for ATLAS will be described. If the IEEE-488 port receives a valid command, the power supply will switch automatically in 'EXTERN/Interface' mode. In this mode are all programming possibilities ineffective, only the overvoltage threshold can be programmed (by means of the 'OV-ADJ' trimmer or remote) lower than the value programmed on the BUS. - Page 25 Remove on the power switch the jumper J1 and J2 c) Note: In the unit for 115 VAC the OV-funktion is clamping. To reset the OV, turn the line switch off and on again. Fig. 14 Atlas 2000 Page 25 von 26 ISSUE 07/05...
