EVSE For Level I & Level II Charging Stations
The C8000 Automated Test System for EVSE is a standard test platform that will perform the standardize test outlined by SAE J1772.
The demand for EVSE is steadily growing as Electric Vehicles and Hybrid Electric Vehicles gain popularity, unlike the conventional gas station, which mainly consists of mechanical parts, the EV/HEV charging station has sophisticated electronics for metering, controlling, and measuring the amount of energy required and transferred to the vehicle.
Charging Station Characteristics
| Level | Nominal Supply Voltage | Maximum Current (Amps) | Circuit Breaker (Amps) |
| I | 120 VAC, 1ɸ | 12A | 15A (Minimum) |
| II | 120 VAC, 1ɸ 208 to 240 VAC, 1ɸ | 16A < 80A | 20A Per NEC 625 |

61500 Series AC Power Sources
- 61500 Programmable AC Power Sources
So embedded usually means DC-powered electronics sometimes run by batteries. But military systems are different: They can require high DC voltages (28 VDC for vetronics) and even high-current AC in many airborne platforms. Alternating current is more efficient in these instances and is eventually converted into DC for the electronic suites.
Digital Power Meters
- Meets Energy Star Measuring Requirements
The 66201 Digital Power Meter is packaged in a 2U high, half rack enclosure suitable for bench top or system integration and includes simple measurement functions designed for low power applications (maximum current 2A).
Model 66202 Digital Power Meter includes a 2-shunt design to provide highly accurate readings for both low and high current measurements. In addition to the parameters measured by Model 66201, the 66202 includes Inrush current, Total Harmonic Distortion of V/I, and Energy measurements. With these practical functions, The Model 66202 is suitable for the most demanding of R&D and quality control departments.
AC Electronic Loads
- Measure Critical Timing Parameters: UPS, Battery, Off-grid Inverters
Chroma's 63800 AC Electronic Loads are designed for testing uninterruptible power supplies (UPS), Batteries, Off-Grid Inverters, AC sources and other power devices such as switches, circuit breakers, fuses and connectors. Equipped with unique timing measurement functions, the 63800 Loads allow users to measure critical timing parameters such as battery discharge time, the trip time for fuse and breaker testing and UPS transfer time.
