2024: Presentation of the WM-500VA, WM-1000VA, WM-2000VA, WM-3000VA, WM-5000VA line
The Powercom company presented on May 21, 2024 a line of relay voltage stabilizers: five new models - WM-500VA, WM-1000VA, WM-2000VA, WM-3000VA, WM-5000VA in the capacities corresponding to names.
These are single-phase relay devices designed to power household electrical appliances with a stable voltage within the framework of GOST (230V). The WM series stabilizer models have 7 adjustment stages, which allows them to effectively adjust the input voltage upward (boost mode) or downward (buck mode). They support an extended input voltage range (~ 105-285 ± 3% V), which guarantees uninterrupted power supply to connected equipment even in critical conditions of the network. All models are equipped with built-in thermal protection of the autotransformer.
Power and load terminal connections are provided only in the WM-500VA model. The rest of the models are equipped with standard CEE7/4 (EU) sockets with reliable fixation of any type of plugs - WM-500VA and WM-1000VA (one outlet each), WM-2000VA (two outlets), WM-3000VA (three outlets).
In the electronic circuit of stabilizers, a microprocessor is installed, which helped to endow the devices with some useful functions, such as:
- increased accuracy of output voltage stabilization,
- displaying the current input/output voltage value on the LED display of the faceplate,
- LED indication of stabilizer operation modes,
- "PAUSE" function with adjustable delay of power supply (within 6 or 180 s) at its resumption,
- protection against overvoltage/undervoltage in the network,
- protection against RF and pulse interference,
- protection of the stabilizer against overload and short circuit.
The Powercom WM series voltage stabilizers have an original modern design and are made in a durable metal case (only 7.2 cm and 8 cm thick) with wall mounting.
The official manufacturer warranty is 24 months. The service life is 5 years.
