Engineered for mission-critical generator starting, Automatic Mains Failure (AMF) panels, VCB control circuits, and harsh grid conditions across Southern Africa.
In the contemporary South African industrial and commercial environment, power reliability presents an unprecedented operational challenge. With utility-scale grid instability, frequent Stage 1 through Stage 6 loadshedding schedules, and severe voltage fluctuations during power restoration events, local enterprises depend heavily on secondary power backup infrastructure. At the absolute core of this standby ecosystem sits the diesel generator set (genset). However, a generator is only as reliable as its starting battery—and that battery depends completely on the precision, robustness, and thermal performance of its automatic battery charger.
As leading global manufacturers of industrial Switch-Mode Power Supplies (SMPS) and automatic battery chargers, Micro Power (manufactured under Sanstar Microsystems Pvt. Ltd.) delivers high-reliability power electronics specifically tailored to the environmental and electrical demands of South Africa. From the humid coastal operations of Kwazulu-Natal to the extreme thermal variations of the Highveld and mining sectors across the Rustenburg Platinum Belt, our industrial battery chargers ensure standby diesel engines crank reliably every single time grid utility power fails.
Information Gain Note: Unlike consumer-grade trickle chargers, industrial SMPS battery chargers designed for South African Automatic Mains Failure (AMF) panels must feature high surge immunity, wide operating input ranges (90V AC to 290V AC), temperature-compensated float charging, and reverse polarity protection to prevent catastrophic battery sulfation during multi-cycle daily grid outages.
Historically, standard control panels utilized heavy, low-efficiency line-frequency transformer chargers. Under continuous municipal grid stability, these basic chargers were sufficient. However, under daily back-to-back load shedding, traditional linear chargers reveal catastrophic design limits:
Modern industrial micro-grids require High-Frequency Switch-Mode Power Supply (SMPS) Chargers equipped with multi-stage automated charge algorithms (Bulk, Absorption, and Float modes), active power factor correction (PFC), and potential-free alarm contact outputs for seamless Integration into Building Management Systems (BMS) and SCADA networks.
Designed for installation inside AMF switchgear panels, generator control boxes, and distribution boards. Micro Power units provide clean, low-ripple continuous power while conditioning starter batteries.
Operates effortlessly between 90V AC and 290V AC input voltage. Resists deep grid sags in rural farming zones and neutral-line shift surges in dense industrial parks across Gauteng.
Transitions smoothly from Constant Current (Bulk) to Constant Voltage (Absorption) and trickle Maintain (Float) mode, maximizing starter battery lifespan by up to 300%.
Equipped with built-in short circuit, overload, over-voltage, over-temperature, and reverse battery polarity protections. Self-recovering upon fault removal.

From telecommunications towers situated in remote terrain to underground extraction shafts, our battery chargers provide reliable industrial DC power.
Mining operations require maximum uptime for underground ventilation, dewatering pumps, and safety systems. Generators operating in dusty, high-vibration environments demand chargers with conformal-coated PCBs, robust metal enclosures, and severe immunity against electrical noise caused by high-power variable frequency drives (VFDs).
Cellular base transceiver stations (BTS) and data centers require continuous power. Micro Power SMPS chargers integrate low electrical ripple (< 1% peak-to-peak) to prevent signal interference while maintaining 24V DC backup batteries for engine control modules, relay logic, and remote telemetry units (RTUs).
Private and public hospitals across South Africa are legally required to restore power within 10 seconds of utility failure. Our fast-response automatic chargers ensure 12V and 24V starter batteries remain fully charged, supporting emergency life-support machinery, operating theatres, and cold storage units.
Automatic Mains Failure (AMF) panel builders specify our compact DIN-Rail SMPS chargers due to their low heat dissipation, space-saving footprints, and compliance with South African National Standards (SANS) electrical codes.
The South African energy sector is undergoing a rapid transition. Companies are combining rooftop solar PV systems, battery energy storage systems (BESS), and diesel backup generators into hybrid microgrids. This shifts the role of the backup generator from an occasional emergency measure to a frequently cycled daily component.
Micro Power (Sanstar Microsystems Pvt. Ltd.) brings over 30 years of specialized power electronics expertise. Operating from state-of-the-art facilities, we maintain strict quality controls, complete magnetics winding in-house, and perform 100% full-load burn-in testing on every power unit produced.
Our senior application engineering team is ready to evaluate your load profile, enclosure limitations, and environmental requirements to build a custom industrial charging system.
Our chargers utilize an automated 3-stage switch-mode charging profile (Bulk/Boost, Absorption, and Float). When grid power is restored, the charger immediately enters Bulk Boost mode (delivering maximum rated current up to 10A/20A) to quickly replenish the battery within short grid windows before safely dropping into float mode to prevent overcharging.
Yes. Standard Micro Power chargers are engineered with a ultra-wide AC input range of 90V AC to 290V AC. Even if the incoming mains sags to 130V AC during heavy industrial line loading, the charger maintains stable DC output voltage and charging current without dropping out.
Absolutely. Our battery chargers provide ultra-clean regulated DC output with ripple voltage under 1%, making them 100% compatible with modern digital AMF controllers, engine ECUs, CANbus communications, and sensitive diagnostic sensors without causing electronic noise interference.
Micro Power chargers feature solid-state and fuse-protected reverse polarity circuits. If reversed, the charger automatically inhibits output current without damaging internal semiconductors. Once corrected, normal automatic charging resumes immediately.
We provide direct export logistics serving South African distributors, panel builders, and OEMs. Complete documentation (CE, UL, BIS certificates, datasheets, test reports, and HS Code documentation for customs clearance) is provided with every shipment.
