5. Nhazi ntuziaka
- Iwepu: Carefully remove the power supply and all accessories from the packaging. Verify that all components are present (power supply unit, power cord, test leads, user manual).
- Ntinye Voltage Nhọrọ: Locate the 110V/220V switch on the rear panel. Use a flat-head screwdriver to set the switch to match your local AC power voltage (110V for North America, 220V for most of Europe and Asia). Failure to do so may damage the unit.
- Nkwanye: Place the power supply on a stable, level surface, ensuring adequate ventilation around the unit. Do not block the fan vents on the rear panel.
- Njikọ ike: Connect the provided power cord to the power outlet on the rear panel and then to a grounded AC power outlet.
- Ike izizi: Press the instrument power switch on the front panel to turn on the unit. The displays should illuminate.
6. Ntuziaka ọrụ
6.1 Isi Voltage na Ntọala dị ugbu a
- Ensure the power supply is on and no load is connected to the output terminals.
- Ntọala Voltage: For CH1 or CH2, press the respective Voltage Adjustment Knob (14 or 7) to activate adjustment. Turn the knob to set the desired voltage. The 4-digit display allows for precise adjustments.
- Setting Current: For CH1 or CH2, press the respective Current Adjustment Knob (17 or 6) to activate adjustment. Turn the knob to set the desired current limit.
- Ibu njikọ: Mgbe ịtọchara vol achọrọtage and current, connect your load to the appropriate output terminals (15 for CH1, 12 for CH2, 9 for CH3).
- Enable Output: Press the CH1 Output Switch (5) or CH2 Output Switch (13) to enable power output to the connected load. The display will show the actual output voltage na ugbua.
Note on Output Switch: When enabling output, especially with sensitive loads, there can be a brief current overshoot. It is recommended to set voltage and current limits with the output disabled, connect the load, and then enable the output. For highly sensitive circuits, consider using an external switch or connecting the load after the power supply has stabilized.

6.2 Series and Parallel Mode Operation
The MPS-3010H-3 allows for easy configuration of CH1 and CH2 in series or parallel mode:
- Nkwadebe: Ensure both CH1 and CH2 outputs are disabled.
- Họrọ Ụdị: Press the One-key Series/Parallel Function Button (18). The corresponding indicator light (19) will illuminate for either SERIES or PARALLEL.
- Ụdị usoro: In series mode, the output voltage of CH1 and CH2 adds up (e.g., 30V + 30V = 60V), while the current remains at the set limit of the master channel. The display will show the combined voltage na ugbua.
- Ụdị Ndekota: In parallel mode, the output current of CH1 and CH2 adds up (e.g., 10A + 10A = 20A), while the voltage remains at the set limit of the master channel. The display will show the combined current and voltage.
- Enable Output: After selecting the mode, enable the output for both channels.
6.3 Protection Functions (OCP/OVP/OTP)
- OCP (N'elu Nchedo Ugbu a): If the output current exceeds the preset limit, the power supply will enter constant current (CC) mode, limiting the current to the set value. The CC indicator will light up.
- OVP (N'elu Voltage Nchedo): Ọ bụrụ na mmepụta voltage exceeds a preset maximum, the power supply will shut down the output to protect the load.
- OTP (N'elu Nchekwa Okpomọkụ): If the internal temperature of the power supply exceeds a safe operating limit, the unit will automatically shut down to prevent damage.
6.4 Ntọala ndị ọzọ
- Ụda igodo: The power supply features an option to turn off the key sound for a noise-free experience. Refer to the on-screen menu for this setting.
- Ọnọdụ ebe nchekwa: The unit retains its last settings upon power-off and restores them when powered on again.
