elneos® five | 43 Technical data and features of the optional comfort equipment (optional, Ref. No. EL5.C) Master/Slave function (optional) Optional interlinking of two regulating power supply units, e.g. 1 master regulating power supply unit and 1 slave regulating power supply unit. The slave regu- lating power supply unit follows the nominal values of the master regulating power supply unit and sup- plies the same voltage at the output. Both channels are galvanically isolated from one another. Characteristic Due to the newly developed bidirectional master-slave function it is of no importance which power control unit is for the master and which one for the slave. As soon as a parameter (either U or I) is changed in a control unit, the parameter of the second control unit follows the first control unit and vice versa. This is a bidirectional function of a high degree of flexibility. Symmetrical/asymmetrical tracking function The tracking function serves for the simultaneous withdrawal of a negative and a positive voltage which are linked. This function is activated by simultane- ously switching on the function serial and ratio. Classical tracking function – symmetrical voltages with reverse sign With a symmetrical withdrawal of the negative and positive voltage, both voltages are adjusted at the beginning to an identical value. Example: Power control unit 1 is adjusted to +10 V. Power control unit 2 is adjusted to +10 V. When changing the voltage value, the other voltage value follows the same way, however, with a reverse sign. Extended tracking function – asymmetrical voltage with reverse sign The ratio function allows also asymmetrical adjustments. Example: Power control unit 1 is adjusted to +10 V. Power control unit 2 is adjusted to -5 V. When changing the values as follows: power control unit 1 is adjusted to +20 V (doubling), power control unit 2 follows and adjusts itself to -10 V. Serial/parallel function (optional) Due to the internal relay interconnection, the two outputs are switched in series or in parallel. This allows the taking of either the double amount of voltage or the double amount of current. Characteristics of serial interconnection • Possibility when withdrawing any positive and negative voltage. • Coloured indexing of cumulative voltage by 2 diagonally arranged and illuminated sockets in red and blue.The two other diagonal sockets are illuminated in turquoise. • The individual voltage of the normal laboratory sockets are measurable in parallel anyhow. Characteristics of parallel interconnection • Coloured indexing of the two masses by illuminated sockets in light blue. • Display of the cumulative current of power control unit 1 and power control unit 2. • Linking of both parameters of current and voltage (simultaneous change). Ratio function The ratio function links the voltage channel of the power control unit 1 with the one of power control unit 2 and vice versa. This helps in particular to simulate asymmetric loads. Example: Power control unit 1 is adjusted to +10 V. Power control unit 2 is adjusted to +1 V. (10% of the value of control unit 1) When changing the voltage of power control unit 1 to 20 V, the ratio function being activated, the power control unit 2 changes to 2 V. With the ratio function the voltage value of the second power control unit follows percentaged the voltage value of the first power control unit and vice versa (ratio). elneos five – experience the touch Power supply unit comfort equipment
