M1~M3，3 sets of memory functions，Store commonly used data and quickly call output

1. Memory core functions
Function Description
Parameter storage saves the current set voltage (V), current (A), power (W), OVP/OCP protection values
Quickly call and switch to stored parameter combinations with just one click, without the need for repeated manual settings
Independent storage M1, M2, M3 are independent of each other and do not interfere with each other
High end models support parameter retention after power failure (non-volatile storage)
Typical storage content:
Output voltage (such as 5.0V, 12.0V, 24.0V)
Output current limit (such as 1.0A, 3.0A, 5.0A)
Overvoltage protection (OVP) threshold
Overcurrent protection (OCP) threshold
Other programmable parameters (such as timing control, LIST mode settings)
2. Typical application scenarios
(1) R&D testing
M1: Store low voltage and low current mode (such as 3.3V/0.5A, used for MCU testing)
M2: Storage power mode (such as 12V/2A, used for sensor power supply)
M3: Store high-power mode (such as 24V/5A, used for motor drive testing)
(2) Production line testing
M1: Storage standby mode (5V/0.1A, used for standby current testing)
M2: Storage full load mode (12V/3A, used for maximum load testing)
M3: Storage overvoltage test mode (15V/OVP=16V, used for circuit verification protection)
(3) Automated testing (SCPI control)
Quickly switch modes by sending instructions via RS232/USB/GPIB (such as Memoriy1)
Implement automatic loop testing using scripts (such as M1 → M2 → M3 → M1...)
3. Operation method (taking a typical model as an example)
(1) Store current parameters
Set target voltage, current, OVP/OCP and other parameters
Long press M1 for 3 seconds to save the current configuration
Repeated operations can be stored in M2 and M3
(2) Call storage parameters
Short press M1/M2/M3 to switch directly to the corresponding mode

★OCP Function ★OVP Function

1. OCP (Over Current Protection)
Function: When the output current exceeds the set safety threshold, the power supply automatically cuts off the output or limits the current to prevent equipment damage caused by short circuits, overloads, or abnormal loads.
Trigger condition:
Load short circuit or abnormally low impedance.
Sudden increase in load power (such as at the moment of motor start-up).
The power supply itself malfunctioned, causing the current to lose control.
Protected object:
Internal components of the power supply (such as MOS transistors, transformers, etc.).
External connected load devices.

2. OVP (Over Voltage Protection)
Function: When the output voltage exceeds the set value, the power supply immediately shuts off the output or clamps the voltage to avoid high voltage damage to sensitive loads (such as chips, circuit boards, etc.).
Trigger condition:
Power feedback loop failure (such as voltage regulator circuit failure).
External interference or transient voltage surges (such as lightning strikes).
Incorrect operation (such as manually adjusting the pressure too high).
Protected object:
Load equipment (especially electronic components with low voltage resistance).
The output stage circuit of the power supply itself.

★Encoder precision adjustment

In DC power supplies, an encoder knob is a common human-machine interaction component used to adjust output voltage, current, or other parameters. Compared to traditional potentiometers, encoder knobs have advantages such as digital control, high precision, and long lifespan.
Function implementation of encoder knob
(Parameter adjustment)
Voltage/current setting: Rotate the knob to change the target value, with adjustable steps (such as coarse/fine adjustment mode).
For example, the step size is ± 0.1V for fast rotation and ± 0.01V for slow rotation.
Advantages of Encoder vs Potentiometer

Characteristic encoder knob, traditional potentiometer
Adjustment method: digital signal (no physical wear), analog resistance (mechanical wear)
High precision (accurate to mV/mA level) and low precision (affected by resistance linearity)
Function extension supports interactive functions such as pressing and holding, and only rotation adjustment
Lifespan: Millions of rotations, thousands to tens of thousands of rotations

Typical application scenarios
Laboratory programmable power supply: Quickly and accurately set voltage/current, supports OCP/OVP threshold adjustment.
Industrial power control: on-site parameter modification is achieved through knobs and display screens.
Multi channel power supply: switch between different channels and independently adjust parameters.
