KUAIQU DC Power Supply Variable, Regulated Bench Power Supply for Fast Recharge, Equivalent to adding a BMS to your battery

🔥Our adjustable DC switching power supplies (models SPS‑C3010S, SPS‑C605S, SPS‑C1203S and SPS‑C305S) undergo burn‑in testing with different load resistors before shipment, ensuring customers receive only qualified products.

🔥Differences between the PCB boards of other brands' switching power supplies and the KUAIQU SPPS-C605C PCB board

For other brands' PCB boards:
1, Small common-mode choke with thin windings, low-spec filter components, only meeting basic EMI requirements with poor anti-interference.
2, Small main transformer with low-grade magnetic core, insufficient power margin, easy to overheat under long-term full load.
3, Only one 880μF-class large capacitor on the high-voltage side, average output filtering, weak ripple suppression and low redundancy.
4, Chaotic PCB layout, no effective isolation between high/low voltage circuits, excessive flying wires/manual connections, irregular traces, poor EMC design and low mass production consistency.
5, Thin PCB traces, weak high-current carrying capacity, high overheating risk at full load.
6, Small heat sinks, crude thermal design, loose component arrangement, easy to overheat under long-term full load and short service life.

PCB Board of KUAIQU SPS-C605C:
1, Large-volume common-mode inductor with thick magnetic core and full windings; higher-spec filter components deliver strong EMI suppression and better input stability.
2, Large main transformer with high-grade magnetic core and thicker windings, providing sufficient power margin to support long-term full-load operation.
3, Multiple large capacitors in parallel (5 high-capacity electrolytic capacitors on high-voltage and output sides combined) offer larger total capacity, excellent ripple suppression, purer output voltage and full design redundancy.
4, Compact and reasonable layout with clear separation between high-voltage and low-voltage circuits; regular and thick copper traces, high proportion of SMD components, automated soldering, mature mass-production design (marked BR300 REV.1.3), ensuring excellent consistency and reliability.
5, Robust traces for high-current paths deliver strong current-carrying capacity, excellent heat control and support for long-term high-load use.
6, Large fan plus rational component arrangement ensures sufficient heat dissipation for high-heat components; complete over-temperature protection guarantees long service life and high reliability.

Battery Charging DC Power Supply

R-SPS High Power Battery Charging Series DC Power Supply are designed for charging batteries. The DC Power Supply can charge a wide range of battery types within it's voltage range. Such as lithium batteries, lead-acid batteries, LiFePO4 batteries, etc.

The DC power supply has a maximum voltage of 60V, and can charge batteries below 60V, such as 6V/12V/24V/36V/48V/60V batteries.
Common Battery Charge Current and Charge Voltage:
Charging voltage = 1.15 * battery rated voltage.
Charging current = 0.1C~1C ("C" is the battery capacity).

WARNING: Please note that the above recommendations do not represent all battery types, and you should check the proper charging voltage and current before charging.

Core advantages

🔥intelligent charging
🔥Short circuit detection
🔥Real-time Ah display
🔥Fully charged self stop
🔥Common voltage and current storage function
🔥Output Switch
🔥Check the total battery capacity

Output Switch

The DC power supply is equipped with an output switch, you can set the voltage/current value you need first, and then turn on the output switch, then the DC power supply will have output voltage/current.

The output switch prevents the connected load from being damaged.

OCP

"Short-circuit killer" is a colloquial term for various risk sources or fault modes that can cause circuit short circuits, leading to severe consequences such as equipment damage, fire, or explosion. It is commonly used in the electronics, electrical, and battery fields. The core cause is the direct connection between positive and negative poles or live and neutral wires due to insulation failure, which generates an instantaneous large current and high temperature.

Intelligent Fan

When the operating temperature of the DC power supply exceeds 122°F or 50°C, the fan will turn on intelligently to dissipate heat effectively. Reduces the working noise of the DC power supply and prolongs the service life of the DC power supply.
