Description of commodity waterproof scales CAS BW-150RB
Product scales CAS BW, waterproof are designed for weighing goods, products and materials that leave behind traces of contamination. They have a dust and water protection design, designed for operation in rooms with high humidity and / or dust content.
Commodity electronic scales CAS BW are designed for operation in difficult production conditions - with high humidity, high concentration of dust, etc.
Due to the waterproof design (protection class IP-65), CAS BW scales will serve as an ideal choice for working with dusty, damp and wet products (tea, flour, meat, fish, cottage cheese). The device is widely used in wholesale and retail trade, industrial and warehouse enterprises, including agriculture.
Other advantages include - wide functionality, stainless steel platform. steel, offline mode power supply and several modes of operation.
Advantages of commercial waterproof scales CAS BW:
- Swiveling and tilting of the BI type weighing indicator
- Waterproof version according to IP-65 class (except for model BW(BN)-500), the sensor is sealed
- Limit stops for mechanical protection of the sensor
- Mains powered via adapter or batteries
- Large LCD display with 2-way swivel capability
- Automatic power off during breaks
- Selection of tare weight from the entire weighing range
- Comparator and counting modes of operation (determining the number of identical objects)
- Weight averaging under unstable load
- Dosing regimen
- Weighing unstable loads
- Membrane keyboard
- Low battery indication
- Battery powered
- Stainless steel platform

I was forced to write a review by a message I received from an unknown buyer of Aliexpress: “Write someone a review of how it works.” I promised, but employment did not allow me to fulfill the promise on time. Unknown, sorry, but better late than never.
The device is simple, but necessary. And, as Capitan Evidencia will write: "Intended for testing power supplies - blocks, batteries, chargers."
Seller's choice - at the time of ordering, this one had the cheapest price (there was another one with a price a few cents cheaper, but no reviews at all). The rest raised prices for the seventh anniversary of Aliexpress, and I already lost coupon 3 from 25, so the purchase cost me $ 26.34. Now, perhaps you can find a load, a dollar or two cheaper than others. As a plus for this seller, I want to write down careful packaging, a solid cardboard box, bubble wrap and voids filled with foam plastic fragments and scraps of the same film (handmade), and this is important in this case, and unexpectedly fast delivery.
The build quality is very decent. Printed circuit board, radiator, cooler do not cause any complaints, the elements stand exactly, the soldering is accurate and there are no traces of flux. The device is pleasant to take in hand. There is no smell of any basement industry, and even in the stable phrase "factory China" you can safely remove the word "China".

Compared to the popular Chinese load of 35W.
What you need to pay attention to.
Operation requires an independent 12V power supply, using the tested source to power the EV may result in an uncontrolled load or other unpredictable situation. 
I got an adapter from a Chinese monitor.
First, power is connected to the load, and then the source under test. Incorrect connection polarity can damage the device. It is better not to connect the source when the load is running (not to be confused with it turned on or, if you like, powered). If you set the current to 10 A, start the EN, and then connect a 60 V source, then the instantaneous power can reach 600 W, although the load current is automatically reset, but it needs a reaction time of about 0.02 seconds, during which time the device may fail . It is useful to control your actions when working with the device and understand what consequences they should lead to.
Work with load:
1) Connect the power and if the screen shows “ Welcome to use”, and the buzzer squeaked happily, the device is ready for operation.
2) Press the "Set" button to move the cursor (underscore " I=0 9
.00
"), and "Add" / "Decrease" to change the value according to the position of the cursor. When the cursor is at the " I" or " V”, press the “Increase” or “Decrease” button to switch the current current and voltage setting mode. 
3) Connect the EH to the power source to be tested, observing the polarity. Evaluate the source voltage in the upper left corner of the screen. 
If you connect only the “V” terminals, then the EN will work like a banal voltmeter.
4) Click the "Start" button to start/stop the e-boot operation, at the same time, the screen in the upper right corner displays " ON» / « OF».
5) Press the "Start" button for more than 1 second to reset the amp-hours and time, and the electronic load will turn off.
6) In the lower left corner, by default, information about power, ampere-hours, temperature and time is displayed and changes every two seconds. Press and hold the "Set" button, then press the "Add" button to select the display of one value you want. If you want the information to switch automatically again, press and hold the Set button, then press the Zoom Out button until " Auto».
7) The voltage and current settings are automatically saved after power off.
8) The maximum load power in continuous operation is related to the ambient temperature. If the temperature is too high, the power must be reduced. If the heatsink temperature reaches 87°, the load will automatically reduce power. When the temperature reaches 91 ° (do not understand how to enter the EN load into this mode, but apparently just in case such protection is implemented), it stops working and must be started manually after cooling.
9) The load current will be automatically adjusted according to the input voltage. For example, if it is set to 10A and the input voltage is 20V, it will automatically change the actual current to 7.5A (150W/20V).
10) The load will automatically turn off if the source voltage drops below the set value, while the inscription “ O.V.” (off volts?).
11) Don't forget to reset the reading if amp-hour and time statistics are required. By default, they accumulate and can only be reset manually.
12) You can change the brightness of the LCD backlight with a trimmer resistor.
Controller - 15F2K16s2.
ADC - MCP3421
Transistor IRFP250N.
Doesn't count watt hours. 150 watts dissipates, but at what temperature I don’t know (I think +5 degrees), at +19 it dissipates 110 watts.
Thanks to the respected kirich, who gave me the idea, I calculated that theoretically EN will dissipate 150 watts for a long time at an air temperature of + 13.87 degrees Celsius (on a scale for the most fundamental).
Findings:
The device does what it claims to do very well. I recommend to purchase.
Performance check video and temperature tests:
UPD.
Who is really interested:
Air temperature +12, 140 W (14 V, 10 A) -30 minutes temperature is stable 85.
40 minutes - temperature +11 140 W temperature 82.
90 minutes +11 140W 82 (stable state)
120 minutes +10 140 W 81 (stable)
3h15 min +11 140 Tue 82.
By the way, weather anomaly.
The experiment is over.
Conclusion 2: Elves live on MYSKU who want to get an electronic load and a cooling system for it for 30 bucks. It is desirable at a discount and with a coupon of 29.99 from 30, then also cut down the refund from the seller - "does not correspond to the declared characteristics." Here I have a 140 watt processor in my computer, I understand that I need a heatsink with coolers for it, and without making any claims to the seller of the processor, I go and buy Noctua NH-D15 and I am sure that everything will work for me at an air temperature of +40 degrees, for 7750 rubles. Before you scold the load, invest $110 and everything will work as advertised. Miracles don't happen. I plan to buy +17 Add to favorites Liked the review +19 +32
