NOTA: El producto se encuentra en Tlaquepaque Jal. y se hacen envios a toda la republica Mexicana. Checa en la opcion de costos de envios para mayor inf............
Nota: Se hacen entregas en el area cercana a centro Sur en GDL previo acuerdo.
Convertidor DC-DC tipo buck VARIABLE, te baja el voltaje de salida vs la entrada (Reductor) de 5A, alta eficiencia, 75W maximo,
Nota: El voltaje de entrada siempre debe ser mayor que el de salida.
Te sirve para fuentes variables, fuentes para alimentar LED de potencia, fuente de poder para el rango establecido, etc
Puedes controlar tanto corriente (CC) como voltaje (CV) con cada potenciometro por separado.
PCB color azul o rojo: Ambos tienen las mismas funciones y se despachan segun disponibilidad rojo o azul.

Application
1 Use as a step-down modules with overcurrent protection capabilities
Usage:
(1) adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
(2) use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a
predetermined overcurrent protection value. (For example, the meter displays the current value of 4A, then you
can use the module to a maximum current of 4A)
(3) Connected to the load.
2 Use as a battery charger
Usage:
(1). Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh,
then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)
(2). Under no-load conditions, adjust the “Voltage potentiometer” so that the output voltage reaches the float voltage;
(if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)
(3). use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a
predetermined Charging current value.
(4). Charge turn lamp current factory default is 0.1 times the charging current; (Battery during charging current is
gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned
off, the green light is on, which means that the battery is fully charged)
(5).connected to the battery charge.
(1,2,3,4 steps as: Output is unloaded, do not connect the battery)
3 Use as a LED constant current driver module
Usage:
(1). adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
(2). use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a
predetermined LED operating current.
(3). Connect LED, work.
(1,2 steps as: Output is unloaded, do not connect LED)
Package included:1 x 5A Lithium Charger CV CC buck Step down Power Supply Module LED Driver
