ACPv4 - Reducing Air Conditioning Costs in Multi-room Buildings
ACPv4 is an external power switch designed for the automatic
turn-on/off of air conditioning systems. It significantly
reduces electricity costs in multi-room buildings such as
offices, schools, governmental and municipal institutions, while
protecting the A/C unit from excessive switching and improper
voltage.
The automatic shutdown and activation function operates based on
a predefined time programmed on the PCB, a motion detector, or
manual user settings.
ACPv4 is designed for heavy-duty operations. It has microswitch
buttons to allow excessive pressings and uses a contactor for
high currents. Relay can also be used for medium/low horsepower
units.
ACPv4 can be customized to meet customer requirements, including
options for installation with or without an electrical socket,
single-phase or three-phase compatibility, and mounting either
on the wall or aligned with the wall’s surface line.
MAJOR REDUCTION IN ELECTRICITY COSTS
- Allows using separated A/C unit for each room
-
Eliminates the expensive cost when people live the room and
forget to switch off the A/C unit
SIMPLEST AND EFFICIENT USABILITY
- No need for remote control or complex timer programming
- Perfect for residences who don’t care about the building
owner’s bills…
PROVEN, ROBUST, SOLUTION
- More than 300,000 ACPv4 units have been installed
- Average of 10 years of product life

TFR Electronic Relay – Phase Failure and Sequence Relay
The TFR Electronic Relay is designed to protect electrical installations and distribution panels from improper operation due to missing phases, reverse phase sequence, or voltage drops in one or more phases. It ensures reliable operation in both utility power grids and generator-based systems.
Key Features:
- Suitable for use with both generators and utility power networks.
- Operates without the need for a neutral (N) line.
- Compact design for space-saving installations.
- Adjustable sensitivity for precise operation.
- LED indicator for normal operating status.
Technical Specifications:
- Power supply: 3-phase 400VAC
- Frequency: 50Hz
- Power consumption: 2.3VA
- Monitors phase sequence
- Voltage imbalance detection range: 7%–15% across all three phases, with a 2% operating threshold
- Phase loss detection: 20%–40% drop in one phase
- Repeat accuracy: 1%
- Relay contacts: 1 changeover contact (1CO)
- Maximum contact current: 16A
- Operating temperature range: -5°C to +60°C
- Mounting: DIN rail compatible
Built for robust and precise monitoring, the TFR relay helps prevent damage and operational faults in sensitive electrical systems, offering both reliability and long-term performance.

ES-VP – External Socket Voltage Protector
External-Socket Voltage-Protector (ES-VP) is a
precision-engineered device designed to protect electronic
equipment from damage caused by improper voltage levels. ES-VP
continuously assesses incoming electrical current and
automatically disconnects power when voltage readings fall
outside safe operating parameters. This ensures that connected
devices receive stable, regulated power, significantly reducing
the risk of damage from surges, sags, or fluctuations.
A key differentiator of ES-VP is its
exceptional robustness and extended operational lifespan.
Constructed using high-grade materials and reinforced internal
components, ES-VP delivers consistent performance under
demanding conditions. Its superior durability and reliability
distinguish it from comparable products.
Technical Specifications:
- Input Voltage: 230V
- Frequency: 50Hz
- Maximum Relay Contact Current: 16A
- Maximum Power: 3500W
- Overvoltage Cutoff Threshold: 250V ±2%
- Undervoltage Cutoff Threshold: 190V ±2%
- Connection Delay Time: 10 seconds
- Sockets Protected by Varistor
