14.4V/28.8V Bi-Voltage
For ALEXA LF/65 and all normal cameras
The great solution to power ARRI Alexa LF/65
high voltage cameras: SWIT Intelligent Bi-voltage Battery, which can output both 11-16.8V
normal voltage and 22-33.6V high voltage,
with auto recognition and switching by the
dedicated V-mount plate, compatible with
Alexa LF/65 and all other normal cameras and
devices, with no risk of misusing.
14.4V/28.8V Auto Switching
By Alexa dedicated plate KA-A20S
The Bi-voltage battery PB-H290S output normal
11-16.8V voltage as default, you can attach to any
normal V-mount cameras or other devices, and any
normal voltage chargers. Use the ARRI ALEXA dedi-
cated V-mount plate KA-A20S, PB-H290S battery can
recognize and auto switch on 22-33.6V, to power
Alexa LF/65/SXT/AMIRA.
* KA-A20S Plate:
CNC metal housing, High load power pins,
D-tapx2 (16V), 2-pin LEMO (16V), USBx1 (5V/2A)
Officially Recommended by ARRI
14.4V/28.8V Auto Switching
By “Magic Sticker” on normal V-plates
Beside ALEXA cameras, many Cine Lights are also
designed high voltage input, to reduce current ef-
fectively, and protect power pins and ensure the
reliability.
You can easily put on a “Magic Sticker” on the par-
ticular position of all standard V-mount plates,
then PB-H290S battery can recognize and auto
switch on 22-33.6V output mode.
290Wh Capacity, 250W High Load
PB-H290S consists of 24pcs high class 18650 battery cells,
and reaches 290Wh high capacity.
PB-H290S supports Max 250W constant power output, can
drive ALEXA LF (160W) more on-camera monitors or wireless
simultaneously.
The high load battery will have longer life time than normal
battery if always under full load power.
6A Super Fast Charging
Using SWIT super fast charger
PB-H290S supports 6A fast charging by SWIT S-3812S or PC-P460S super fast charger, to save up to 60% charging time, can be charged from 0 to 80% after 2 and half hours, and fully charged within 3 hours 50 minutes.
D-tap Socket
A D-tap DC output socket is equipped on the top side of the
battery pack, to power the other on-camera equipment together.
Under 14.4V (11-16.8V) output mode, D-tap output
11-16.8V and Max load 120W/10A;
Under 28.8V (22-33.6V) output mode, D-tap output constant 16V and Max load 50W/3A;
Digital Power Indicator
8-LED remaining time read
When battery is discharging:
Press "Power Check" button, Upper 4 LEDs display remaining working hours, and Lower 4 LEDs display remaining working minutes, under current output power. The LED will flash when remaining time is less than 15 minutes to remind changing battery.
When battery is charging:
Upper 4 LEDs flashing constantly, indicates the real-time capacity percentage 25%, 50%, 75% and 100%.
When battery is free:
Press "Power Check" button, Upper 4 LEDs light up, to indicate the remaining capacity percentage 25%, 50%, 75% and 100%.
Strong 1.5m Drop-off Proof
Dual housing + Rubber cover
PB-H290S has innovative dual housing structure: the inner cell cage and outer anti-shock housing with rubber covers. The new structure
makes the battery quite strong, anti-shock. The battery can survive from 1.5 meters any angles drop-off.
Ultra Low Standby Power
Holds Power for Years Without Losing Charge
Ordinary batteries can be damaged after
long-term storage due to complete power
drainage.
SWIT batteries adopt a unique low-power
design that could hold the charge for several
years without losing power. There is no need
for regular charge-discharge maintenance,
just effortless, reliable storage when you
need it.
