ABB LOW VOLTAGE PRODUCTS

Mon, 23 Mar 2026 08:33:03 GMT

Raise & Lower is an authorised supplier and system integrator of ABB’s premium low voltage components, including circuit breakers, contactors, starters, and protection devices. These components are known worldwide for their reliability, safety, and performance.

Low-voltage products are electrical devices designed to operate at relatively low electrical voltages (commonly ≤1000 V AC or ≤1500 V DC in power distribution, and often ≤50 V in electronics or control systems). They are widely used in mining, commercial buildings, factories, and automation systems for safe power distribution and control.

Below are common types of low-voltage electrical products used in electrical systems.

1. Circuit Protection Devices

Used to protect electrical circuits from overloads and short circuits.

These devices control motors, lighting, HVAC systems, and industrial machinery.

Understanding the Role of Thyristor Power Controllers in Industrial Efficiency

Wed, 15 Oct 2025 13:47:29 GMT

Raise and Lower (Pty) Ltd provides specialised systems for power factor correction and thyristor-based motor control. These solutions help reduce energy waste and improve the efficiency of electrical infrastructure.

Thyristor Power Controller

A thyristor power controller is an electronic device used to control and regulate power in AC or DC electrical systems, typically for high-power industrial applications. It uses thyristors (also known as SCRs - Silicon Controlled Rectifiers ) to switch and modulate the electrical power delivered to a load, such as a heater, motor, or lighting system.

How It Works

A thyristor acts as a switch that can be turned on by a gate signal, but can only be turned off by stopping the current flow (commutation). The controller adjusts the conduction angle (the portion of each AC cycle during which the thyristor conducts), thereby controlling the average voltage or power delivered.

There are two main methods:

Phase Angle Control - Delays firing of thyristors in each AC half-cycle.
Burst Firing (Cycle Control) - Turns full AC cycles on/off in bursts (used when electrical noise must be minimised).

Main Components

Thyristors/SCRs
Triggering/Driver Circuit - Provides gate pulses.
Control Circuit - Uses feedback (e.g., temperature, voltage) to regulate output.
Heat Sink - Since thyristors dissipate heat.
Protection Circuitry - Overvoltage, overcurrent, etc.

Applications

Industrial Heating (resistive load)
Motor Speed Control
Transformer Soft Start
Power Supplies

Advantages

High efficiency
Precise power control
Long lifespan (no mechanical contacts)
Low maintenance

Disadvantages

Generates harmonics (especially with phase control)
Needs good heat dissipation
May require filtering (EMI/RFI)

Powering Efficiency with Thyristor Power Controllers

In today's industrial landscape, energy efficiency and precise control are no longer optional; they're essential. Thyristor power controllers offer a robust, reliable, and highly adaptable solution for managing power delivery in demanding applications. From controlling heat in manufacturing processes to optimising motor performance, these controllers provide unmatched versatility and longevity.

Whether you're upgrading your electrical infrastructure or engineering a new system from the ground up, integrating a thyristor-based power solution can drastically reduce energy waste, minimise downtime, and boost overall system performance.

VARIABLE SPEED DRIVES (VSD) & SOFT STARTERS

Wed, 17 Sep 2025 08:38:16 GMT

1. Variable Speed Drives (VSDs)(Also known as: VFDs – Variable Frequency Drives , or AC Drives)

Raise and Lower supplies and installs Variable Speed Drives and soft starters to control motor speed and protect against electrical surges.

Purpose:

To control the speed and torque of an electric motor by varying the frequency and voltage of the power supplied to the motor.

How It Works:

Converts incoming AC power to DC.
Then inverts DC back to controlled AC with variable frequency /voltage.
The frequency determines motor speed.

Main Features:

Full control over motor speed.
Allows energy savings at reduced speeds.
Can provide torque boost at startup.

Typical Applications:

HVAC fans and pumps
Conveyors
Elevators
Mixers
Any application requiring variable speed control

Advantages:

Energy-efficient (especially for variable load applications)
Precise motor control
Reduced mechanical stress during start/stop
Can reverse motor direction electronically

2. Soft Starters

Purpose:

To gradually start and/or stop an electric motor by controlling the voltage ramp-up (not speed control).

How It Works:

Uses thyristors or similar semiconductors to slowly increase the voltage to the motor during startup.
Motor reaches full speed at full voltage.
Main Features:
Soft start/stop
Limited to full-speed operation
Reduces inrush current and mechanical shock

Typical Applications:

Pumps
Compressors
Fans (when speed control isn’t critical)
Conveyor belts (simple start/stop control)

Advantages:

Simple and cost-effective
Reduces mechanical wear and tear
Smaller size and easier installation

Improves power quality during startup

In Summary:

Choose a VSD if you need variable speed, energy savings, or precise motor control.
Choose a Soft Starter if you only need to reduce startup current and protect mechanical parts during startup/stop, but don't need speed control.

Ready to improve energy efficiency and extend the life of your equipment? Whether you need advanced motor speed control with a Variable Speed Drive or a cost-effective Soft Starter solution, Raise and Lower is here to help. Our expert team supplies and installs the right systems for your needs, ensuring reliability, performance, and long-term savings.

Understanding Distribution Panels: Components, Types, and Applications

Wed, 27 Aug 2025 10:10:19 GMT

A distribution panel (also called a distribution board, breaker panel, or electrical panel) is a key component in any electrical system. It serves as the central hub that distributes electrical power from a main source to multiple circuits throughout a building or facility. Raise and Lower (Pty) Ltd has a long history and experience in this industry.

Definition:

A distribution panel is an enclosure that houses protective devices like circuit breakers, fuses, and sometimes relays. Its job is to divide incoming electrical power into separate circuits and provide protection through breakers that trip during overcurrent or short circuits.

We are able to assist in any of the key components as listed below as separate entities or even as a complete Distribution Panel ( manufacturing to the customers specifications)

Key Components of a Distribution Panel

Types of Distribution Panels

Applications

Commercial buildings - For lighting, HVAC, server rooms
Industrial facilities - Heavy-duty panels for machines, motors, welding equipment
Construction sites - Temporary panels for tools and lighting

Safety & Compliance

Must comply with standards SANS9000\SANS90001
Proper earthing/grounding is critical
Use lockable enclosures for security and safety

Custom Fabrication

In steel fabrication, distribution panels often require custom enclosures, especially for:

Outdoor use (IP65, weatherproofing)
Corrosive environments (stainless steel or powder-coated steel)
Compact spaces or integrated machinery panels

Contact Raise And Lower

Ready to upgrade or install a customised distribution panel for your facility? At Raise and Lower (Pty) Ltd , we specialise in designing and fabricating panels tailored to your exact specifications, ensuring safety, compliance, and efficiency.
