1. Please use a power cord that meets the power requirements of this product
2. Before use, the power supply must be grounded reliably, and the weak leakage
current caused by the internal anti-electromagnetic interference circuit of the power
supply should be led to the ground, otherwise “false leakage will occur which may
cause damage to the load equipment or cause the power supply to resist interference
decrease in ability.
3. When using this power supply to charge reusable batteries (such as lead-acid
batteries), be sure to connect the positive and negative poles of the power supply to
the positive and negative poles of the battery correctly.
4. If the connection is reversed, it may burn out the internal rectifying parts of the
power supply, or damage the load equipment.
5. It is strictly forbidden to use this product in an environment with flammable,
explosive materials, humidity, and corrosive gas.
6. When this product is working, it will generate heat. especially under full power
usage, Therefore, please use this product in an environment with good ventilation
and heat dissipation, and ensure that there are no other obstacles in the vicinity of
the product’s cooling fan and vents
7. When using this power supply, please select an output wire with sufficient wire
diameter according to the output current of the product. The connection area
between the wire and the power supply, the wire and the load equipment is large
enough, the contact surface is clean and free of corrosion, and the connection must
be firm to avoid heat damage to the terminal or load equipment, which may cause a
fire in severe cases.
8. If you encounter product use problems and quality problems, please consult our
after-sales personnel. If necessary, the power supply must be sent to our company
for maintenance. Because there is a high voltage inside the machine. (Even if the
power is off, the circuit will still have high voltage for a certain period of time.)
Please do not repair or modify it by yourself. otherwise. it may cause the expansion
of the fault or cause personal injury.
9. Please confirm the AC voltage allowed by the machine first. This machine can
realize two kinds of AC voltage input through the switch on the rear panel: AC
230V ± 10% or AC 115V ± 10% (when “230V” appears, allowable input
voltage:AC230V±10% when “115V” appears, allowable input voltage: AC 115±

1.BPS1203 Programmable DC power supply with power display 120V 3A
2.BPS3010 Programmable DC power supply with power display 30V 10A
3.BPS605 Programmable DC power supply with power display 60V 5A
4.BPS305 Programmable DC power supply with power display 30V 5A
DIAIARY’s new series products. This model is a miniature switching DC power supply. The output voltage and current can be controlled and adjusted by variable resistors respectively, so it provides more convenience and accuracy in the adjustment of voltage and current. The panel also provides high-precision two/three-window digital tube display of voltage, current and power, so that users can intuitively see the current use status and various parameters of the machine
