In traditional testing scenarios, the sole mission of an electronic load is to “consume”. The DC power output by the device under test is almost completely converted into heat, which is then dissipated by fans or burned off by resistors. This one‑way consumption approach is being re‑evaluated by more and more enterprises as energy costs continue to rise.
The emergence of regenerative electronic loads has completely broken this pattern. Ningbo Zhimao’s IPDC2000 series DC regenerative electronic load is not a traditional “energy consumer”; it is an energy transfer station – it efficiently converts the DC power generated during testing into AC power and feeds it back to the grid. That is why some say: the IPDC2000 is more than just a load; it is a miniature power station.
A Technological Revolution from “Power Consumption” to “Power Generation”
To understand the energy‑saving value of the IPDC2000, let’s start with some numbers: a traditional 10kW load consumes over 10kW of electricity during testing, almost all of which turns into heat. Additional high‑power air conditioning is then required to dissipate that heat, creating a vicious cycle of “test consumption and even more consumption for cooling”.
The IPDC2000 adopts a DC/DC bidirectional two‑stage circuit and a three‑phase PFC regenerative design. Through fully digital PWM rectification technology, it achieves complete electrical isolation. Its energy regeneration efficiency exceeds 93%. Under rated conditions, the input power factor is greater than 0.99 and the harmonic content is less than 3% – the current quality is clean enough to be fed back to the grid without concern. In other words, for every 100 kWh of electricity consumed for testing, at least 93 kWh are recovered and reused, truly enabling energy recycling.
More Than Energy Saving: Comprehensive Testing Capabilities
Energy regeneration is just the starting point. The IPDC2000 series covers a power range from 50kW to 500kW, supports a maximum DC voltage input of 1200V, and can be flexibly adapted to various scenarios from R&D laboratories to production line burn‑in. In terms of operating modes, it supports constant voltage (CV), constant current (CC), constant power (CP) and constant resistance (CR), meeting the precise simulation requirements of different test conditions. Its built‑in BMS simulation function can realistically emulate the working state of a power battery. Together with an external national‑standard charging gun socket, it provides a complete one‑stop solution for whole‑machine testing, protocol verification and ageing tests of DC charging piles for electric vehicles.
Safety Assured, Control Worry‑Free
High‑power grid‑connected testing challenges not only efficiency but also safety. The IPDC2000 integrates multiple automatic protections including short‑circuit, overcurrent, overload and overtemperature, ensuring stable operation even under long‑term high‑current discharge. The device also features a power‑on self‑test function to eliminate potential hidden faults in advance. Communication interfaces come standard with RS232, RS485, CAN and Ethernet, enabling remote control and data management via a PC. Discharge current, discharge time, discharge capacity and other parameters can be customised to meet flexible testing requirements.
The Economics: Payback Within One Year
From a practical return perspective, the IPDC2000 offers an extremely short payback period. Take a new‑energy charging pile manufacturer as an example: its production line burn‑in runs 24 hours a day, maintaining a test power level of around 300kW. After switching to the IPDC2000, annual electricity savings exceeded RMB 600,000, while cooling requirements and main power configuration were reduced by 90%. The equipment investment was recouped in less than one year. When hidden benefits such as reduced power supply capacity, downsized plant air conditioning, and extended equipment life are also considered, the payback period can be shortened even further.
In today’s context of the deepening “dual carbon” strategy, green testing has changed from a “nice‑to‑have” to a “must‑have”. The IPDC2000 series, with its 93% regeneration efficiency, wide power coverage, flexible multi‑mode configuration and comprehensive safety protection system, provides enterprises with a test equipment upgrade path that delivers both economic and environmental benefits.
