KD100 Vector Variable Frequency Inverter AC Drive
Single phase three phase 0.75kw 1.5kw 1hp 2hp 220v solar pump
inverter
K-EASY KD100 pump inverter Features:
1. Cover voltage levels 220V AC and 380V AC.
Support single-phase 220V and three-phase 220V/380V pumps,the power
from 0.4KW to 37KW.
2. Easy to use
The inverters automatically start or sleep only after being
connected to solar battery panels without any parameter setting.
3. Highly reliable for using multiple protective measures
Including PV over-voltage protection,PV polarity reverse
warning,and auto derating against over-temperture,which extend
product life.
4. Use advanced MPPT algorithms,ensuring that the solar power
tracking efficiency reaches 99%
5. Models of 2.2kW or lower can be configured with boost
module,meeting low-voltage work requirements.This reduces the use
of solar battery panels and therefore the cost.
6. it can implement auto switch between solar input and grid input
by configuring the boost or auto switching cabinet(meeting
lightning protection requirements),implementing 24-hour unattended
work.

08. High precise torque constraint, process PID control, multi-speed
control, contracting brake control, field weakening control, all
sides protection, etc;
09. Online and offline auto-tuning of motor parameters can both
performed;
10. Extremely short-time acceleration can be performed without any
trip, such as 0.1s or 0s from 0Hz to 50Hz;

Applications
KD100 drives are economical series at K-Drive. They offer V/f
control, including voltage and frequency separated control,
adaptable to various industrial applications if sensor-less vector
control is not required, including printing machines, packaging
machines, pumps, fans and blowers, etc.
Production
In production, rigorous quality control is implemented on
components, circuit boards, and the finished goods, assuring
products without defects.
