Why choose Communica for power kits and assemblies
When a project needs reliable power - from classroom labs and prototyping benches to workshop installations - the difference is in the components, the advice and the speed of delivery. Communica offers deep local stock of power modules, supplies, batteries, converters and wiring essentials so you can get from spec to build without long overseas lead times. We focus on practical selection, compatibility notes and accessory bundles that save time on sourcing and testing.
Immediate value for South African teams
Benefit-driven support includes stock checks at our Samrand head office, branch collection in Pretoria CBD or Cape Town, VAT invoices for procurement, and quotation paperwork tailored for education and business purchasing. Our stock covers global brands and maker favourites you'll recognise, and our quoting process captures delivery and lead-time options so procurement is never a guessing game.
What’s included in a typical power kit quote
- Primary supply: SMPS or bench PSU selected to match voltage and current requirements
- Protection: fuses, circuit breakers, and surge suppressors where appropriate
- Conversion: buck/boost converters and DC-DC modules for distributed rails
- Interconnect: connectors, cable sets and labelled wiring harnesses
- Accessories: mounting, enclosures, terminal blocks, and test leads
When you request a quote we produce a clear bill of materials with part numbers and alternatives, plus accessory bundles that speed installation (eg. pre-crimped leads, heatshrink kits, and panel-mount AC inlets). That means fewer order rounds and faster build times.
Specification callouts we verify for every quote
To avoid mismatches we confirm: input voltage range (90-264VAC vs 115VAC), DC output voltages and tolerances, continuous current rating and thermal derating, ripple/noise for sensitive electronics, and connector pinouts. We also note any special shipping or handling for batteries and high-voltage assemblies.
If you want to browse product ranges before quoting, explore our shop by category or see all stocked components in our product index. For brand-specific modules and maker boards, our shop by brand page helps you match exact part numbers.
Quick technical checks we handle for you
Provide the desired rails and loads and we’ll run the checks: power budget, heat dissipation, and connector current ratings. Example calculation we use internally: if a 5V rail needs 8A and a 12V rail needs 3A, total continuous DC power = (5V*8A) + (12V*3A) = 40W + 36W = 76W. We size supplies with a safety margin (typically 20-30%) and note derating at high ambient temperatures for on-site installs.
Need to see stock or collect? Check branch hours and collection options at our branches & trading hours. We keep quotes actionable - with lead-time ranges and pickup options clearly shown so project managers can schedule installs with confidence.
Compatibility guidance, bundles and practical tips
Compatibility issues are the most common source of delay. We flag mismatches early: plug types, barrel sizes, PSU pinouts, and polarity. For multi-rail systems we recommend labelled harnesses and standard connector families (e.g., Anderson, XT30/60 for battery feeds) and provide accessory bundles for neat installations - cable ties, ferrules and panel-mount fuse holders included.
Common bundles and recommended pairings
- Bench prototyping kit: bench PSU + banana leads + multimeter + safety glasses
- Embedded dev kit: 12V DC supply + buck regulator + header-mounted screw terminal adapter
- Backup power kit: Li-ion battery pack enclosure + BMS module + DC-DC boost converter
Each bundle is quoted with alternatives so you can compare specs quickly. Use our internal comparison guidance to weigh ripple, efficiency and thermal performance rather than price alone.
Objection handling: lead times, VAT & procurement
Concerned about lead times? Our quotes include stock status and realistic ETA ranges. If a component is special-order, we propose local alternatives where available and mark long-lead items clearly. For institutional purchases we provide VAT invoices and quotation documentation formatted for procurement teams.
If you need reassurance on part fitment, request a technical note with the quote and we’ll show connector pinouts, mechanical dimensions and a simple wiring diagram like the example below:
AC IN ---[IEC inlet]---[EMI filter]---[SMPS]---+5V ---+---(to board)
| +--- fuse
+12V --+---(to motor driver)Specifications at a glance
| Spec | Typical Option A | Typical Option B |
|---|
| Output | 12V 10A (120W) | 5V 20A (100W) |
| Ripple | < 50mV | < 30mV |
| Cooling | Passive heatsink | Forced air (fan) |
