Introduction

The model PeakTech
6060 high-precision DC regulated power supply has two ways adjustable output. The two adjustable outputs can also be selected for constant voltage or constant currant,  designed in high stability and performance circuit. In a constant voltage state, the output voltage can be arbitrarily from 0 V on the nominal range; and in the state of constant current, the output current can be adjustable from 0 A on the nominal range. The two outputs can be connected in parallel or in series, while the master used for voltage or current adjustment. The maximum output voltage in series is double of independent’s, and the maximum output current in parallel is double too.
There are volt and Amp meters (or 3-digit LCD) for indicating each of the two outputs with high accuracy. The one fixed way output 5 V voltage. Due to the single chip integrated regulator, this output has good stability and ripple factor and has reliable overload protection to protect the unit against being damaged whenever overload or short circuit.
The units features in small size, good performance, a novel appearance and etc, it is the ideal power supply unit for science investigation, college, factory, electronic appliance maintenance and etc. This power source can be fitted into 19″-racks and can be used as a “stand-alone”-unit.

Permanent operations
This model of the power supply provides 2 adjustable outputs for a maximum current of 10 A, which can be connected in series or parallel, which means a maximum output of 20 A  DC in parallel.
This performance is designed only for short time applications and not for permanent operations.
For longer life, it is recommended to use up to 75% of the maximum values for permanent operation.

3.2. Operating method
Independence use of two adjustable outputs.

1. Press switch (7).
2. When the adjustable output is used as CV output, first should rotate clockwise the CC adjustment (2) and (17) to maximum, then turn on the power switch (13), adjust CV  adjustment (4) and (14) till the output voltage reach required voltage value, at this time, the CC state indicator (1) and (11) go out the CV state indicator (3) and (12) light on.
3. Used as CC output, after turning on the power switch (13), first rotate clockwise the CV adjustment (4) and (14) to maximum, while rotating counter-clockwise the CC  adjustment (2) and (17) to a minimum, connect the required load, again adjust clockwise adjustment (2) and (17) till output current reach the required current value. At this time, the CV state indicator (3) and (12) go out and the CC state indicator (1) and (11) light on.
4. Used as the CV output, in general, the CC adjustment (2) and (17) should be set to maximum, but for this unit, the current-limiting protection point can also be set arbitrarily.
   Setting procedure: turn on the power, rotate counter-clockwise the CC adjustment (2) and (17) to a minimum, then make the positive and negative output terminal in short connection and rotate clockwise the CC adjustment (2) and (17) till output current equal to the required current-limiting protection point, so the current-limiting protection point is well set.

Series using of the two adjustable outputs.

1. Press the switch (8). At this time, turn the master voltage adjustment (14) and the slave out voltage tracks strictly the master output voltage, and the output voltage can be up to double of independent´s maximum voltage (voltage between terminal (18) and (23).

2. Before the series connecting, it must be examined if the negative terminal of both master and slave output is connected to the case grounded terminal, if they are, must be disconnected, otherwise, short-circuit will be caused in the slave output when the two outputs are connected in series.

3. When the two outputs are in series, the voltage is controlled by the master output, but the current adjustment to the two outputs is still independent. Therefore, attention should be paid to the position of the CC adjustment (2) and (17). For example, knob (2) is at the position counterclockwise to the end or current of slave output excesses current limiting protection point, at this time, the voltage of slave output will not track the voltage of the master.
   So knob (2) should be rotated clockwise to maximum then the two outputs are in series.

4. This unit can be output from the front panel and rear panel at the same time.
   When use the unit as bench type, it is better for you to use the front panel outputs, and when you use the unit as rack mount type, it is better for you to use the rear panel outputs. Of course, you can use both front panel outputs and rear panel outputs at the same time.
   The output current should be the summation of both front-panel outputs and rear-panel outputs.

Parallel use of the two adjustable outputs.

1. Press the switch (9).
2. At this time, the two outputs are in parallel, adjust voltage adjustment (14) of the master output is, the voltage of the two ways keeps the same, and the slave output CC indicator (1) lights on.
3. When the two outputs are in parallel, the CC adjustment (2) of slave output does not work. When used as CC supply, simply adjust the CC adjustment (17) of master output, at this time, the output current of both master and slave output is controlled by it and are the same, output current is up to double (20 A) of independent’s maximum current.
4. While the two outputs in parallel, since the unit has relay switch control, the two positive terminals and the two negative terminals of the master, and slave output and shorted reliably and separately by the relay inside the unit.
   You can connect the load directly between terminals (18) and (20), (21) and (23), (18) and (23). For output current balance, connecting the load between terminals (18) and  (23) is recommended.
   The LED displays are in three digits.

Caution

1. This unit has excellent protection function, 5 V output has reliable protection for current-limit and short. The two adjustable outputs have current-limit protection. As there is a controlling circuit for regulating the transistor’s power loss in the circuit, when short-circuit occurs, the power loss on large power transistors is not very high, it can’t cause any damage to the unit. But there is still power loss when short-circuit, in order to reduce aging and energy consumption, so this situation should be found as soon as possible and turn off the power, then exclude the faults.
2. When operating is finished, put it in a dry place of good ventilation, and keep it clean. If it is not in use for a long period, pull off the power supply plug for storage.
3. For maintenance, the input voltage must be cut off.
