Introduction

The PeakTech® 6215 is a precision-controlled laboratory power supply with high efficiency. The PeakTech ® 6215 features four outputs: two variable outputs 0 V – 30 V with current limiting function and two outputs with 0 V – 6.5 V/3 A; 0 V – 15 V/1 A. Additionally, the power supply provides a constant voltage mode, constant current operation mode, overvoltage protection, and overload protection function.
The voltage and current values for the variable outputs are adjusted linearly and can be switched with the aid of the internal circuit automatically in parallel or in series. Thus, the operation in series mode has a maximum output voltage of 60 V, in parallel operation, the maximum output current is 10 A.
The high stability of this power supply is suitable for use in schools, training, laboratory, university, and service.
